Given: RNA codon chart and DNA sequence of the enzyme. Make 2 amino acid changes:1. Proline to Glycine2. Tyrosine to Phenylalanine a) what are the steps required to make these changes, in order? b) transcribe the following DNA sequence into mRNA: 3’ TAC CCC GAT AAA ATA CAT TTA GGA TCG CGA TGG TAT 5’
Answers
Answer
1. To change from Proline to Glycine
Step 1: Change the DNA of proline
Proline has the following four condons: CCG, CCC, CCU, and CCA.
And the Glycine codons are: GGT, GGG, GGA and GGC
So if the codons of Proline can be changed, C to G, we will have CCG, CCC, CCU, and CCA.
Which are the same as the codons of Glycine, when the tRNA translates, these will be amino acids of Glycine.
2. To change Tyrosine to Phenylalanine
The codons of Tyrosine are: UAU, UAC, UAA and UAG
Whereas the codons for Phenylalanine are: UUU, UUC, UUA and UUG
change the A to U in Tyrosine to get Phenylalanine
So the final Tyrosine codons will be: UUU, UUC, UUA and UUG.

C) I and III only
D) II and III only
Answers
The claim that is supported by the data observed in the graph is Agricultural crops are more efficient than meat production per square meter.
Why are agricultural crops more efficient than meat production per square meter?Agricultural crops are generally more efficient than meat production per square meter for several reasons.
These reasons include:
Energy efficiency: Crops require less energy to produce compared to meat. This is because growing crops requires less energy input, such as feed, water, and other resources, compared to raising animals for meat production.Land use efficiency: Growing crops is more land-efficient than raising animals for meat. Crops can be grown more densely and can yield more food per unit of land than livestock can. This is because animals require more space to move around, graze, and obtain their food.Water use efficiency: Crops require less water to produce than meat. Water is required for both crops and livestock, but it takes significantly more water to produce a unit of meat than a unit of crops. This is because animals require water for their own needs as well as to produce the feed that they eat.Environmental impact: Meat production has a higher environmental impact compared to crop production. Livestock produce methane, a potent greenhouse gas, as well as other pollutants. Raising animals also requires more land, water, and other resources, which can lead to deforestation, water depletion, and other environmental issues.Overall, agricultural crops are more efficient than meat production per square meter due to lower energy input, higher land use efficiency, lower water use, and a lower environmental impact.

what are some basic things about genetics and how they function (need for a one pager)
Answers
People receive their parents' chromosomes, which house their genes. The 23 pairs of the 46 chromosomes that make up the human genome total 46. Chromosomes are paired. One set of each pair of chromosomes—one from the mother and one from the father—is randomly inherited by a child from each parent.
Genes serve a variety of purposes.
As parts of genetic material, genes are also units of inheritance.
They regulate the phenotypes or morphologies of individuals.
Cell division requires the replication of genes.
Hereditary information is passed down from one generation to the next through genes.
Here are five genetics-related facts.Genetics: Interesting Facts
About 90% of the genetic material in mice and 98% in chimpanzees is shared by humans. A nearly complete copy of the human genome is found in every cell of the body. Both our mother and father contribute 23 chromosomes to us. Genes can be passed down to cause some diseases.

12. A man has the X-linked dominant condition CGH that produces dense hair on the face and upper body. What is the chance that he will pass it on to his daughters?
Answers
Answer:
Explanation:
The probability that the daughter of a mom with a dominant disease-causing allele on the X chromosome and a dad with the disorder will be affected with the disorder is 100%. This is because the daughter will inherit one X chromosome from the mom, which carries the dominant allele that causes the disorder, and one X chromosome from the dad, which is affected by the disorder.
Since the parents are unaffected, we can infer that they are both heterozygous carriers of the Lesch-Nyhan syndrome allele. If they have a son with the syndrome, we know that the son inherited the recessive allele from both parents. The chance that a daughter of this couple will inherit Lesch-Nyhan syndrome is 25%. This is because the daughter will inherit one X chromosome from the father, which does not carry the recessive allele, and one X chromosome from the mother, which has a 50% chance of carrying the recessive allele.
Since the condition is X-linked dominant, the man will pass on the dominant allele to all of his daughters. Therefore, the chance that he will pass it on to his daughters is 100%.

Answer: I predict that human use of fossil fuels will affect their distribution over time because.
Explanation: Because if we keep on using fossil fuels over and over we eventually loose all of it because nearly 67% of the worlds reserves of crude oil are currently in the Middle East. So if we keep on using it well then there won't be anymore fossil fuels left for us, And if we keep using it, it will also slowly kill us off and also kill everything else around us.
In trying to determine whether DNA or protein is the genetic material, Hershey and Chase made use of which of the following facts?
Answers
Radioactivity was utilized by Hershey and Chase to determine whether DNA or protein made up the genetic material. They used radioactive phosphate to identify the Nucleotide in a T2 phage.
Simply put, what is radioactivity?Radioactivity, as its name suggests, is just the act of generating radiation without any external cause. An fission reaction that is unstable for some reason accomplishes this by "wanting" to give up considerable energy through order to change its configuration to one that is more stable.
Why does radioactivity occur?Radioactivity is the energy released when the nuclei of specific atoms and isotopes decay. Protons and neutrons are linked together in little coils at the centers of atoms to generate their atomic nucleus.

Which of the following nutrient provide more energy? a. Protein b. Carbohydrate c. Lipids d. Vitamins
Answers
The nutrient which provide more energy is C. Lipids
Among the given options, lipids provide the most energy per unit mass. Lipids, also known as fats, are a concentrated source of energy in the diet. When metabolized, lipids yield approximately 9 kilocalories (kcal) of energy per gram.
Carbohydrates, including sugars and starches, provide approximately 4 kcal of energy per gram. They are a readily available source of energy for the body, particularly for short-term energy needs. Proteins also provide approximately 4 kcal of energy per gram. However, their primary role is not as an energy source but rather as the building blocks for tissues, enzymes, and other important molecules in the body.
Vitamins, on the other hand, do not provide significant energy. They are essential for various biochemical processes in the body but do not contribute directly to energy production.
It is important to note that while lipids provide the most energy per gram, the overall balance and variety of nutrients in a diet are crucial for maintaining optimal health. Nutrient needs vary based on individual factors, such as age, sex, activity level, and overall health goals. Therefore, Option C is correct.

Why do alleles from linked genes sometimes appear to follow the law of
independent assortment?
A. During meiosis, alleles can switch between homologous
chromosomes through crossing over.
B. During independent assortment, alleles can select which
chromosome they are on.
C. During mitosis, alleles will move up and down a chromosome to
stay together.
D. During segregation, alleles on the X chromosome can be passed
to other chromosomes.
Answers
The correct answer is:
A. During meiosis, alleles can switch between homologous chromosomes through crossing over.
Crossing over, which occurs during meiosis, is the process where homologous chromosomes exchange genetic material. This can result in the swapping of alleles between linked genes, leading to new combinations of alleles on the chromosomes. As a result, linked genes may appear to follow the law of independent assortment, where alleles are randomly assorted into gametes.
During meiosis, crossing over allows alleles from linked genes to switch places and appear to follow the law of independent assortment.
Explanation:In genetics, alleles from linked genes sometimes appear to follow the law of independent assortment due to the phenomenon of crossing over during meiosis. Crossing over occurs when homologous chromosomes exchange genetic material, resulting in the recombination of alleles on different chromosomes. This process can lead to the separation of linked alleles and the appearance of independent assortment.
For example, let's consider two genes located close to each other on a chromosome. Initially, the alleles for these genes are linked and inherited together. However, during crossing over, a break can occur between the genes, allowing the alleles to switch places. As a result, the alleles can end up on different chromosomes, leading to independent assortment.
Therefore, option A is the correct answer. Crossing over during meiosis allows for the exchange of alleles between homologous chromosomes and breaks the link between genes, resulting in the appearance of independent assortment.

What stage of meiosis is Mendel's law of segregation?
Answers
Mendel's law of segregation is in the phase anaphase of meiosis.
Anaphases I and II of meiosis are where Mendel's Segregation law takes place. The homologous chromosomes are sorted into two daughter nuclei with their different versions of each gene during this stage of the first meiotic division.
The first division of meiosis, during which the homologous chromosomes with their unique versions of each gene are divided into daughter nuclei, serves as the physical basis for Mendel's law of segregation. During meiosis, the two different alleles for a single gene segregate as the chromosomes divide into several gametes, resulting in each gamete acquiring one of the two alleles.
In Mendel's experiments, meiosis-induced segregation and independent assortment in the F1 generation result in the F2 phenotypic ratios that Mendel observed.
