56. Paragraph Which of the following is not involved in the elongation step of translation? A. RNA polymerase B. Ribosomes C. Peptidyl transferase D. Charged tRNA E. The amino acid (A) site
Answers
The component not involved in the elongation step of translation is RNA polymerase.
During the translation process, the amino acid sequence is created by decoding mRNA codons. The second stage of the process is called elongation and refers to the ribosome's movement along the mRNA transcript.
The elongation step is where the polypeptide chain continues to grow, and the ribosome moves down to the next codon.
Elongation factor TU (EF-TU), a GTPase, is a component involved in the elongation step of translation. Charged tRNAs are brought to the ribosome by EF-Tu and their amino acids are added to the growing chain.
The ribosome contains three distinct sites known as the A site, the P site, and the E site. The growing polypeptide chain is held by the P site. The A site holds the incoming tRNA with the anticodon that matches the next codon on the mRNA transcript. The E site holds the tRNA that has finished donating its amino acid to the growing polypeptide chain.
In conclusion, RNA polymerase is not involved in the elongation step of translation. RNA polymerase is an enzyme involved in transcription, the process of making RNA from a DNA template.
Translation is the process by which proteins are synthesized from mRNA transcripts, and RNA polymerase is not involved in this process.

Antibodies bind _________to antigen as part of _________immune response.a.non-specifically; adaptive
Answers
Antibodies bind b. specifically to antigens as part of the adaptive immune response.
This process is essential for the body to identify and eliminate pathogens effectively, the adaptive immune response is a highly specialized system that is tailored to target specific pathogens. It involves the activation of immune cells, such as B cells and T cells, which work together to create a targeted defense against the invading pathogen. When B cells encounter an antigen, they produce antibodies that are specific to that antigen. These antibodies can recognize and bind to the antigen with high specificity, ensuring that the immune response is targeted and effective.
The binding of antibodies to the antigen can neutralize the pathogen or mark it for destruction by other immune cells. In summary, the adaptive immune response relies on the specific binding of antibodies to antigens, which is crucial for effective immunity against pathogens. This highly targeted system ensures that the body can defend itself against a wide variety of foreign invaders.

the blastocoele. c) blastocyst. d) trophoblast.
Answers
The three days post-cleavage, the pre-embryo is a solid ball of cells known as a) a morula.
During the early stages of embryonic development, the fertilized egg (zygote) undergoes a series of cell divisions called cleavage. Around the third day, the pre-embryo forms a solid ball of cells called the morula. This stage is crucial for the formation of the blastocyst, which happens later in the development process.
To describe the morula further, it is a compact mass of cells that typically consists of 16-32 cells. The morula is formed after several rounds of cell division (mitosis) and eventually gives rise to the blastocyst, where further differentiation of the embryo occurs.

In his analysis of different species’ DNA, E.Chargaff discovered the base-pairing rules of DNA.
1.) Chargaff’s rules state: The amount of adenine is equal to ? and the amount of cytosine is equal to ? .
2.) if a sample of jellyfish DNA is 14% cyotsine, approximately how much adenine would there be in that same sample? Show your work.
Answers
Answer:
1. Thymine, Guanine
2. 36% Adenine
Explanation:
1. Edwin Chargaff, who proposed the complementary base pairing rule, stated in his rule that the amount of purine bases (Adenine and Guanine) is equal to the amount of Pyrimidine bases (Cytosine and Thymine). This means that, in a DNA molecule, the amount of adenine is always equal to Thymine (A=T) and the amount of Cytosine is equal to Guanine (G=C).
Also, the total amount of the four nucleotide bases that make up a DNA molecule is equal to 1 or 100% i.e. A+T+G+C= 100%
2. Based on the rule above, if a sample of jelly fish DNA contains 14% Cytosine, the amount of its complementary pair (Guanine) will also be 14%.
Hence, Cytosine and Guanine will collectively occupy 14+14=28% of the DNA.
To find the amount of the other two bases i.e. Adenine and Thymine, we subtract 28% from 100%
That is, 100 - 28 = 72%
If both Adenine and Thymine contains 72% and each must be equal, we divide 72% by 2 to get the amount of each.
Hence, 72/2 = 36% of Adenine and 36% of Thymine.
According to the question, Adenine will contain 36% in the Jellyfish DNA.

You want to study the relationship between daily alcohol consumption and prostate-specific antigen levels. It was suggested that these two parameters have a linear relationship and as you increase your alcohol consumption your prostate-specific antigen level increases. What kind of a linear model would represent this relationship?
Answers
The kind of linear model that would represent this relationship is a positive linear model.
In a positive linear model, as the independent variable (alcohol consumption) increases, the dependent variable (prostate-specific antigen levels) also increases in a linear fashion. This implies that there is a positive correlation between the two variables, suggesting that higher alcohol consumption is associated with higher levels of prostate-specific antigen.
A linear model represents a straight-line relationship between the variables, and in this case, it would show a positive slope. The slope of the line indicates the rate at which the prostate-specific antigen levels increase with each unit increase in alcohol consumption.
By studying this relationship, researchers can gain insights into the impact of alcohol consumption on prostate-specific antigen levels and potentially understand the association between alcohol and prostate health.
However, it is important to note that further research and analysis are necessary to establish a causal relationship and consider other factors that may influence prostate-specific antigen levels.

the higher plant symbiont benefits from the mycorrhizal relationship by principally obtaining which of the following from the fungus.
Answers
Mycorrhizal relationships are mutualistic relationships between fungi and plant roots. The fungus forms a network of hyphae that is much larger than the roots of a single plant. In this way, the fungus can help plants access nutrients that would otherwise be unavailable.
Most fungi get carbohydrates from plants in exchange for nutrients that they've gathered. A mycorrhizal relationship is a good example of this. The fungus gets carbohydrates from the plant, which it uses for energy. In return, the fungus helps the plant absorb water and nutrients from the soil.
Because of the mycorrhizal relationship, plants are able to access nutrients that would otherwise be unavailable to them. The fungus is also able to get carbohydrates that it wouldn't be able to get otherwise. This makes the mycorrhizal relationship a very beneficial one for both parties involved.

Why are complementary base pairs important to the process of dna replication
Answers
For successful DNA replication, it is imperative that complementary bases pair up correctly. The importance of complementary base pairs lies in its ability to ensure the transfer of accurate genetic information with every cell division.
What are the processes of dna replication?The process of DNA replication involves the critical requirement of complementary base pairing to ensure that the genetic information is accurately maintained during cell division. For this purpose, the two strands of DNA double helix undergo separation and act as templates for synthesizing new complementary strands.
The hydrogen bonding between Adenine-Thymine and Guanine-Cytosine allows the bases on each strand to pair accurately with their respective complementing base on the new molecule.
Essential in complementary base pairing is ensuring that the sequence of nucleotides on the new strand perfectly complements the original sequence on the template strand. By doing this, genetic information is transmitted from one generation of cells to another with precise accuracy, thus preventing errors or mutations.

Explanation:
The binding of a compound to an enzyme is observed to slow down or stop the rate of the reaction catalyzed by the enzyme. Increasing the substrate concentration reduces the inhibitory effects of this compound. Which of the following could account for this observation?
1. The compound is a negative allosteric regulator.
2.The compound is a competitive inhibitor.
3. The compound forms a covalent bond with one of the amino acid residues needed for enzyme activity.
4. The compound reduces disulfide bonds, causing the enzyme molecules to partially unfold.
5 The compound causes a cofactor to be lost from the enzyme.
Answers
The correct answer to the given question is option 2. The compound is a competitive inhibitor.
The reason for this is that the compound which is slowing down or stopping the rate of reaction, and which inhibits the enzyme, is known as a competitive inhibitor. A competitive inhibitor is one that binds with the active site of the enzyme, limiting or blocking the substrate from binding with it, thus reducing its activity or stopping the reaction.
Therefore, as the substrate concentration is increased, the competitive inhibitor is more likely to bind to the enzyme, but it is less effective because the substrate concentration is much higher. Hence, it reduces the inhibitory effects of this compound.
A negative allosteric regulator, option 1, would work differently, and would not be affected by the substrate concentration. Covalent bond formation with an amino acid residue or a disulfide bond, options 3 and 4, would affect the structure of the enzyme, rendering it inactive permanently. The loss of a cofactor, option 5, would have a similar effect, but the inhibitory effect would not be reduced by increasing the substrate concentration.
In competitive inhibition, the inhibitor competes with the substrate for the active site of the enzyme. When the substrate concentration is increased, it is more likely that the substrate will bind to the enzyme instead of the inhibitor, reducing the inhibitory effects of the compound.
Hence, the correct answer to the given question is option 2. The compound is a competitive inhibitor.

Early land plants like mosses did not have vascular tissue. They must absorb their water directly from their surroundings, such as growing on rocks or trees that are moist. You find mosses in damp areas for this reason. They cannot grow in drier climates because they cannot pull water from the ground like vascular plants. Ferns are also suited to reproduce in more moist/humid climates because water must be present for their gametes (sperm and eggs) to find one another for fertilization. Seeds are adaptations by angiosperms and gymnosperms that allow for waterless fertilization. Either wind or animal pollinators help spread pollen and help the sperm reach egg cells for fertilization to occur. For that reason, these plants are better suited to survive in drier, modern climates.
