A nucleotide is the building block of nucleic acids
We know that animal populations exposed to higher concentrations of radioactive activity, often suffer deleterious genetic mutations. Thus, the answer would be <u>B.) a higher than average mutation rate.</u>

Explanation:
hope this helps :) the heres the explanation
<h3>
<u>In the DNA strand, we have taken a letter out and put in another letter to see what happens. This method is called substitution, when we take something out, and put a new piece in. </u></h3>

<h3><u>Answer;</u></h3>
<em>Common ancestry </em>
Similar DNA sequences in genes can be evidence of <u><em>common ancestry</em></u>
<h3><u>Explanation;</u></h3>
- <em><u>DNA molecules are fundamental molecules in organisms since they carry genetic information in living organisms.</u></em> DNA sequences similarity among various organisms may be used to establish evolutionary relationship among living organisms.
- <em><u>Many organisms have distinct DNA sequences, however, animals may share some specific types of genes which are similar genetically in the sequences of DNA. </u></em> Organisms or animals whose DNA sequences are similar share common evolutionary origin.
