Question

Sequences can also mutate by the insertion and/or deletion of bases, introducing gaps in the alignment. Let us consider the same two sequences A A T C T A T A and A A G A T A. following alignments below permit gaps, which are indicated by dash symbol. IV. A A T C T A T A A A G A T - - A V. A A T C T A T A A A - G - A T A VI. A A T C T A T A A - A G A T - A Which among these three alignments do you think best illustrates the similarities between the two sequences? Explain how you arrived at your answer.

Explanation / Answer

Nucleotides sequences are complementary base paired, so option (VI) is the answer where most of the nucleotides shows complimentary base pairing.
