A hypothetical human protein sequence is 161 amino acids long.The homologous sequence in chimpanzees is 160 amino acids long.Which modification would most likely be needed to align the sequences?

Question

Quizplus · Accepted Answer

The fact that the human protein sequence is one amino acid longer than the chimpanzee homologous sequence suggests that a gap is needed to align the two sequences. The gap can be inserted in either sequence to align them properly. A substitution or amino acid replacement would suggest a change in the sequence, which is not supported by the given information. Parallel substitution and similarity matrix are not relevant in this context.
