Below are sequences of part of a gene taken from three species of plants.
Plant A: AGATCTACGCGCAGTTTC
Plant B: AGATTAGGCGCAGTATC
Plant C: AGATTAGGCGCAGTTTC
To align these sequences, one should add a gap to species

Question

Below are sequences of part of a gene taken from three species of plants. 
Plant A: AGATCTACGCGCAGTTTC
Plant B: AGATTAGGCGCAGTATC
Plant C: AGATTAGGCGCAGTTTC
To align these sequences, one should add a gap to species

Quizplus · Accepted Answer

By adding a gap to the second position in Plant A's sequence, it can align perfectly with Plants B and C. Therefore, gaps need to be added to Plants A and B to align with Plant C. This means the best choice is to add a gap to B and C only, which is option E.
