The 4 steps of mitosis are Prophase,  Metaphase, Anaphase, Telophase.

The chromosomes shorten and thicken during prophase. Chromosomes align in the centre of the cell during metaphase. Chromatids split off at the centromere and migrate to opposing poles during anaphase. Telophase: Following the reorganisation of nuclear envelopes surrounding each cluster of chromosomes, two nuclei are created.

A centriole that is positioned outside the nucleus splits during the prophase, the first phase. The nuclear membrane vanishes when the lengthy, threadlike substance of the nucleus coils up into the visible chromosomes. Long, fine threads protrude from the centrioles in all directions. The spindle is made up of several of them from one centriole joining strands from the other.

Metaphase, the second stage of mitosis, sees the chromosomes travel onto the spindle's equatorial plane. The third phase, called anaphase, begins when the chromatids divide and move to the opposite ends of the cell. The chromosomes are the split chromatids. A whole pair of chromosomes moves in this way to reach each centriole.

In the telophase, the last step, the cell divides. Contrary to what happened during prophase, the chromosomes uncoil, fresh membranes form around the nuclei, and the spindle fibres disappear. Two identical cells have formed from the original one, and they are now ready to begin their initial growth phase.

The genetic information used to cause cellular processes is c. the order of nucleotides in DNA governs which proteins will be translated.

The order of nucleotides in DNA is responsible for encoding the genetic information necessary for the synthesis of proteins. DNA is composed of a sequence of nucleotide bases, including adenine (A), thymine (T), cytosine (C), and guanine (G).

These bases form specific base pairs: A with T, and C with G.

The segments of DNA that contain the instructions for protein synthesis are called genes. Each gene consists of a specific sequence of nucleotides that encodes the information for a particular protein.

This sequence of nucleotides is transcribed into a complementary messenger RNA (mRNA) molecule through a process called transcription.

During transcription, an enzyme called RNA polymerase binds to the DNA at the start of the gene and reads the DNA strand. It uses the DNA strand as a template to synthesize a complementary mRNA molecule.

The mRNA is composed of nucleotides that are complementary to the DNA template, with thymine (T) replaced by uracil (U) in RNA.

The mRNA molecule then travels from the nucleus to the cytoplasm, where it serves as a template for protein synthesis in a process called translation.

Translation occurs at structures called ribosomes, where transfer RNA (tRNA) molecules recognize specific sequences of three nucleotides on the mRNA, called codons.

Explanation:

Cleansing processes are essential for the removal of pollutants from water bodies. Two common cleansing processes are dilution and bacterial biodegradation. However, these processes have limitations and cannot eliminate all types of pollutants effectively.

Dilution is the process of adding clean water to the polluted water to reduce the concentration of pollutants. While this method can be effective, it requires a large amount of clean water and cannot work if the flow of water is diverted or if the concentration of pollutants is too high.Bacterial biodegradation involves the breakdown of pollutants by bacteria, which can take time and require optimal conditions for effective degradation. This process cannot eliminate slowly degradable or non-biodegradable pollutants effectively.

The oxygen sag curve is a graphical representation of the depletion of dissolved oxygen in water bodies due to the breakdown of biodegradable wastes by bacteria. As the concentration of biodegradable wastes increases, more bacteria are present to break them down, leading to an increased demand for oxygen. This can result in a depletion of dissolved oxygen in the water body, which can negatively impact aquatic life.

The statemnet "the correct pathway for bile is the gallbladder, pancreas, small intestine is false because the correct pathway for bile is the liver, gallbladder, and then the small intestine.

Bile is produced in the liver and transported via the common hepatic duct to the gallbladder where it is stored and concentrated. When needed, the gallbladder releases the bile into the cystic duct, which joins the common bile duct, and finally reaches the small intestine to aid in digestion and absorption of fats. The pancreas produces and releases digestive enzymes into the small intestine, but it is not involved in the pathway of bile.

Bile helps to emulsify fat, breaking it down into smaller droplets that can be more easily digested and absorbed by the body. The pancreas also plays a role in fat digestion by producing enzymes that break down fats, proteins, and carbohydrates in the small intestine.

Answer:

Explanation:

Mutations may or may not affect the phenotype because they can occur in coding or non coding areas of the DNA. If they occur in coding areas of the DNA, the protein that is coded in that part could be processed incompletely or have a different amino-acid in some part of its structure, this would affect the phenotype. If they occur in non coding areas, this would have no effect on the phenotype.

Answer:

The correct order of protein production is:

c) 1,2,4,3

Ribosome: Protein synthesis begins in the ribosomes, which are located either in the cytoplasm or attached to the endoplasmic reticulum.

Endoplasmic Reticulum: After the initial stages of protein synthesis in the ribosomes, the newly synthesized protein is transported into the endoplasmic reticulum (ER) for further processing and modification.

Golgi Apparatus: The proteins synthesized in the ER undergo further processing and modifications in the Golgi apparatus. This includes sorting, packaging, and modifying the proteins to their final functional forms.

Secretory Vesicles: Once the proteins are properly processed and modified in the Golgi apparatus, they are packaged into secretory vesicles. These vesicles transport the proteins to their destination, such as the plasma membrane for secretion outside the cell.

Therefore, the correct order is 1, 2, 4, 3.

Answer:

The correct order of protein production is ribosome, endoplasmic reticulum, Golgi apparatus, and secretory vesicles. So the correct answer would be c) 1,2,4,3.

Many proteins destined for the endoplasmic reticulum, the Golgi apparatus, lysosomes, the plasma membrane, and secretion from the cell are synthesized on ribosomes that are bound to the membrane of the endoplasmic reticulum. The Golgi apparatus then distributes these proteins and lipids that it receives from the ER.

1. Attachment: A bacteriophage attaches to the surface of a bacterial cell.

2. Entry: The viral DNA is injected into the bacterium and integrates into the host chromosome.

3. Prophage: The integrated viral DNA is known as a prophage and is replicated along with the bacterial chromosome.

4. Replication: The prophage replicates along with the bacterial DNA during cell division.

5. Induction: A trigger, such as stress or UV radiation, causes the prophage to leave the bacterial chromosome and enter the lytic cycle.

6. Lytic cycle: The viral DNA begins replicating and producing new phages, which lyse the host cell and release new viruses.

7. Release: The newly produced phages are released into the environment to find other bacterial cells to infect.

Note: The lysogenic cycle can sometimes be followed by the lytic cycle, in which the virus uses the host cell to produce new viruses, ultimately leading to lysis of the host cell.

The function of SDS in buffer ATL is d) it is a detergent that helps disrupt cell membranes. SDS, or sodium dodecyl sulfate, is used to break down the cell membranes and release the cellular components, making it easier to perform further analysis or experiments. The correct answer is option D.

SDS stands for sodium dodecyl sulfate, which is a widely used anionic detergent. SDS is commonly used in biochemistry and molecular biology to solubilize and denature proteins. SDS is a surfactant, which means it decreases the surface tension between liquids and solids. When added to a solution, it causes proteins to lose their structure and unfold, becoming more linear in shape.

Buffer ATL is a tissue lysis buffer used for extracting nucleic acids from mammalian tissue samples, such as blood, liver, and brain, as well as cultured cells. The lysis buffer contains various salts, detergents, and a chelating agent that helps to remove metal ions, which can inhibit the activity of nucleases. This function of SDS is particularly useful in buffer ATL because it helps to break down cell walls and release nucleic acids from the cells. The SDS present in buffer ATL helps to solubilize the cell membrane, allowing other reagents in the buffer to enter the cells and begin the extraction process.

So, the correct option is D.

Most cells are just so tiny that they can't be observed with  eye. Therefore, in order to study cells, scientists must utilize microscopes. Compared to optical microscopes, electron microscopes offer greater magnification, resolution, and detail.

The resolution of light microscopy is well matched to the widths of subcellular structures, and the wide variety of fluorescent probes available makes it possible to label proteins, organelles, as well as other structures for imaging. These characteristics make light microscopy the ideal tool for imaging biology throughout living cells. Most frequently, specific proteins or even other compounds are found in cells and tissues using fluorescence microscopy. Viable cell imaging is an approach that uses time-lapse microscopy to optically study living cells over an extended period of time. In order to be able to see extremely slow activities that are within the limit of human vision, cells can therefore be observed for extended periods of time. Therefore, correlative light/electron microscopy has been primarily used to demonstrate individual proteins in a ultrastructural context (CLEM).

I also got this question right on edge 2021.

Both positive and negative feedback play important roles in the physiology of homeostatic regulation by providing mechanisms to allow the organism to return to homeostasis.

A feedback mechanism may be characterized as the mechanism of the body in order to maintain the levels of hormones in the body to the desired limits. An increase or decrease in the levels of the hormones and enzymes triggers the feedback mechanism.

The process of homeostasis typically involves negative feedback loops that counteract a set of alterations in various properties from their target values. These are known as set points. In contrast to negative feedback loops, positive feedback loops may also amplify their initiating stimuli, in other words, they migrate the system away from its starting state.

Therefore, homeostatic regulations provide mechanisms to allow the organism to return to homeostasis with respect to both positive and negative feedback.
