serious [3.7K]

Out of the following given choices;

<span>A.      </span>The mouse has a completely different DNA sequence than the other mice.

<span>B.      </span> The substituted nucleotide has the same directions as the original nucleotide.

<span>C.      </span>Substitutions in the nucleotides of a mouse's DNA never affect their phenotypes.

<span>D.      </span>DNA sequences don't determine the color of a mouse's fur.

The answer is B. Most probably, the nucleotide substitution did not translate to a change in the amino acid sequence in the translated protein. As you may be aware, most amino acids are coded by more than one codon. For example, Leucine is coded for by CTT, CTC, CTA, CTG, TTA, TTG. Therefore, a substitution, that causes a change to either one of the sequences will not change the amino acid.

denpristay [2]

Answer:

observational learning

Explanation:

Mirror neurons are the neurons present in the frontal lobes and are responsible for observational learning. The action potential fired by these neurons is identical when a person observes an action and when the same action is being performed by the person itself.  

For example, watching a child when he scores good in the examination, a teacher can sense the pleasure felt by him. This is because the teacher imitates the child in her own imagination and plays out the consequences and thereby understands the feeling of the child.
