If an error in transcription causes the last cytosine in an mRNA sequence that was supposed to read UUG AUC CAA UGC to be replaced with a guanine, which of the following do you predict would happen?

Answers

Answer 1

Answer:

If the last cytosine is replaced by a guanine, the last amino acid will become tryptophan instead of cysteine.

UUG AUC CAA UGC.

UUG AUC CAA UGG.

This type of mutation that changes the amino acid is called missense mutation.

In humans, mutations of this type are responsible for diseases such as sickle cell disease. In plants, false sense mutations control, for example, the thickness of the hull of the oil palm fruit.

A characteristic which is influenced by genes and passed from parents to offspring is called heritable. Over many generations heritable adaptive traits become more common in a population. This process is called evolution by natural selection. Evolution by natural selection leads to adaptation within a population. The term evolution by natural selection does not refer to individuals changing, only to changes in the frequency of adaptive characteristics in the population as a whole. For example, for the mice that lived on tan sand, none of the mice had a change in the color of their fur; rather, due to natural selection, tan fur was more common for the pups than for the mother mice. In summary, a heritable characteristic that helps an animal or plant to have more offspring which survive to reproduce and will tend to become more common in a population as a result of evolution by natural selection. a. Explain why a heritable characteristic which helps an animal to live longer will generally tend to become more common in subsequent generations as a result of evolution by natural selection. b. Suppose an unusual heritable characteristic helped animals to live longer but made them sterile so they could not have any offspring. Explain why this heritable characteristic would not become more common in subsequent generations as a result of evolution by natural selection.

It is often possible to predict the number of times a membrane protein crosses the membrane by determining how many short sequences of hydrophobic amino acids are present in the amino acid sequence of the protein. Choose the correct explanation. It is often possible to predict the number of times a membrane protein crosses the membrane by determining how many short sequences of hydrophobic amino acids are present in the amino acid sequence of the protein. Choose the correct explanation. a. Sequences of hydrophilic amino acids are the segments of the protein that span the membrane.
b. Sequences of hydrophobic amino acids are the segments of the protein that span the membrane.
c. Sequences of hydrophobic amino acids are the segments of the protein that dissolve in the membrane.
d. Sequences of hydrophilic amino acids are the segments of the protein that dissolve in the membrane.

Answers

Sequences of hydrophobic amino acids are the segments of the protein that span the membrane. Thus option B is correct.

What are the levels of protein structure?

The Primary structure of proteins is the linear structure of amino acids formed by Covalent, peptide bonds to form primary structure of protein.

Secondary structure protein defined as the folded structures formed by hydrogen bonding among the amine and carboxyl group of the peptide chain and it finally form polypeptide then into protein.

These secondary structure present in two structure such as α – helix which form a polypeptide chain by hydrogen bonding and twisting into a right-handed screw with the -NH group of each amino acid residue.

The β – pleated sheet form of protein are stretched out ,laid side by side together by intermolecular hydrogen bonds.

Answers

Answer:

UUU

Explanation:

A codon is a sequence of three nucleotide bases in a mRNA molecule that specifies an amino acid. During the process of translation, the mRNA strand is read in a group of three nucleotides at a time. A type of RNA called transfer RNA (tRNA) posseses in its structure another group of triplet nucleotides called ANTICODON, which is complementary to the sequence of bases in the mRNA codon.

The tRNA anticodon recognizes and binds to the particular mRNA codon it is complementary to in order to carry the amino acid it specifies to the growing polypeptide chain In this case, the mRNA codon reads AAA. This means that the anticodon on the tRNA that will bind to this codon is UUU.

In the 18th century, a young boy suffered from a skin condition that included thickening of the skin and the formation of loose spines that were periodically sloughed off. This "porcupine man" married and had six sons, all of whom had the same condition. He also had several daughters, all of whom were unaffected. What might you theorize about the location of the abnormal gene?

Answers

The abnormal gene must have been located on the Y chromosome which is responsible for baby boys hence all his sons had the abnormal condition while none of his daughters had the condition.

Genes are the units of inheritance located on the chromosomes. Since the genes are located on the chromosomes, the chromosome involves determines what traits are transmitted.

For the porcupine man, the abnormal gene must have been located on the Y chromosome which is responsible for baby boys hence all his sons had the abnormal condition while none of his daughters had the condition.
