13. DNA sequences are often used to determine relationships between
organisms. DNA sequences that code for a particular gene can vary,
although organisms that are closely related will have very similar
sequences. This table shows the amino acid sequences of 4 organisms.
Based on these sequences, which two organisms are the most closely
related? Explain.
Human:
CCATAGCACCTA
Chimpanzee:
CCATAACACCTA
A Pig:
CCATGTAAACGA
Cricket:
CCTAAAGGGACG
