Molecular Clock

Genetics

The molecular clock is a technique that uses the mutation rate of biomolecules such as DNA, RNA or proteins to estimate the time in prehistory when two or more lineages diverged.

  • Lead section (entity-description)
    The molecular clock is a figurative term for a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged. The biomolecular data used for such calculations are usually nucleotide sequences for DNA, RNA, or amino acid sequences for proteins.
  • Lead section (proposed-year)
    The notion of the existence of a so-called molecular clock was first attributed to Emile Zuckerkandl and Linus Pauling who, in 1962, noticed that the number of amino acid differences in hemoglobin between different lineages changes roughly linearly with time, as estimated from fossil evidence.
