Answer:

The correct answer is option B. "The tRNA that was in the A site moves into the P site".

Explanation:

In the ribosome complex for translation, the A-site (aminoacyl) acts as the point of entry for the tRNA, and the location at which the first amino acid is bound. Once the first codon has been translated into the first amino acid, The tRNA that was in the A site moves into the P-site (peptidyl). The P-site is the second binding site for the tRNA, and the location at which all the following amino acids are added.

I am Lyosha [343]

Answer:

0.50

Explanation:

According to the given information, the frequency of the hornless genotype in the population is = 16% = 0.16. This means that the frequency of the hornless allele in the population is = square root of 0.16 = 0.4.

The gene for the horns in unicorn has three alleles. If the frequency of the allele for twisted horns is represented by "p" and that of the hornless allele is represented as "q", then the frequency of the allele for the longhorn would be (r) = 1- (p+q).

This is due to the fact that the sum total of frequencies of all the possible alleles of a particular gene in a population in the Hardy Weinberg Equilibrium is always 1 (p+q+r =1). Now, putting the values of p and q in the formula to calculate the frequency of allele for the longhorn (r) = 1- (0.1 + 0.4) = 1-0.5 = 0.5

Each of the mutants listed below this paragraph has a different mutant form of the gene encoding protein X. Each mutant gene con
Aleks [24]
It should be taken into consideration the presence of frameshift mutations. Frameshift mutation, due to addition or deletion of a base, results in the change of reading frame and consequently in changed protein. But it is known that 3 nucleotides on mRNA code for the specific amino acid. If the number of inserted or deleted nucleotides is 3, it will result in the absence<span> of only 1 amino acid which is not expected to drastically change protein sequence.
Knowing all this, it can be concluded the following:
</span>
<span>-/-/+/-/- <u>OK </u>- Due to 4 deletions and 1 insertion, effectively only 3 nucleotides are missing.
</span>+/-/+ <u>Not OK</u> - Due to 1 deletion and 2 insertions, effectively only 1 nucleotide is added leading to the frameshift mutation.
+/-/+/- <u>OK </u>- Due to 2 deletions and 2 insertions, a number of nucleotides remain the same.
+/+/-/+ <u>Not OK</u> - Due to 1 deletion and 3 insertions, effectively only 2 nucleotides are added and the frameshift mutation occurs.
-/+ <u>OK </u>- Due 1 deletion and 1 insertion, a number of nucleotides remain the same.
<span>- <u>Not OK</u> - Due to 1 deletion, the frameshift mutation occurs.
</span>-/-/-/-/-/- <u>OK </u>- <span>Due to 6 deletions, it will be deleted 2 amino acids and the protein will be nearly normal.</span>
<span>+/+/+ <u>OK </u>- Due to 3 insertions, 1 amino acid will be added in excess.
</span>-/- <u>Not OK</u> - Due to 2 deletions, the frameshift mutation occurs.
