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

Question

Species 3: Val-Gly-Thr-Ser-Tyr-Pro
• Species 2: Val-Gly-Phe-Tyr-Asn-Pro
Species 1: Gly-Leu-Ser-Thr-Cys-Pro
Species 4: Leu-Val-Met-Thr-Tyr-Pro

Answer 1

Based on the amino acid sequence of the active site, Species 1, which has the sequence Gly-Leu-Ser-Thr-Cys-Pro, would be considered the most evolutionarily related to humans, as it shares the most similar amino acid sequence with the human DNA polymerase gene.
