An amino acid analysis of the DNA polymerase gene in humans determines that the sequence of the active site is: Val-Gly-Thr-Ser-Cys-Pro. Based on this information, which species below would be considered the most evolutionarily related to humans?(1 point)

Question

An amino acid analysis of the DNA polymerase gene in humans determines that the sequence of the active site is: Val-Gly-Thr-Ser-Cys-Pro. Based on this information, which species below would be considered the most evolutionarily related to humans?(1 point)

Responses

Species 2: Val-Gly-Phe-Tyr-Asn-Pro

Species 1: Gly-Leu-Ser-Thr-Cys-Pro

Species 4: Leu-Val-Met-Thr-Tyr-Pro

Species 3: Val-Gly-Thr-Ser-Tyr-Pro

Answer 1

Species 3: Val-Gly-Thr-Ser-Tyr-Pro

Answer 2

Based on the provided amino acid analysis of the DNA polymerase gene, Species 3 (Val-Gly-Thr-Ser-Tyr-Pro) would be considered the most evolutionarily related to humans. This is because it shares the same sequence at the active site as humans, except for a single amino acid substitution (Tyr instead of Cys).
