Question

Which of the following are features of a molecular clock? Select all that apply. Select all that apply. It requires knowledge of age of divergence. It uses the rate at which a gene sequence changes to mark evolutionary time. It works best when rate of change is relatively constant over time. Its use began only 10 years ago.

Answer 1

Option (1), (2) and (3).

Step-by-step explanation:

Molecular clock is a technique used to determine the mutation rate of the biomolecules to deduce its time. The DNA nucleotide sequence or the amino acid sequence of the protein.

The knowledge divergence of the species and its time is important for the construction of molecular clock. The mutation rate can be easily determined to known the evolutionary time. The evolutionary relationship can be best explained if the mutation rate is relatively constant.

Thus, the correct answer is option (1), (2) and (3).
