    Answer: Option A.

    True.

    Explanation:

    Molecular clock is a technique in genetics that use rate of changes of bimolecular to know the time in history since when two or more species have diverged from a common ancestor. The bimolecular data used is nucleotides sequence of DNA and amino acids sequence of proteins. Scientist deduce that protein and DNA evolve at the same constant rate in different organisms.

    True

    Explanation:

    In genetics the figurative term, molecular clock, describes a technique to determine the divergence of two species, it deduces how much time has passed based on the number of differences in a DNA sequence. This technique is valid because the evolutionary rate of change of any protein is fairly constant over time and for different lineages.
