    5. (Biochem.) The copying, by enzymes, of a cell's genome,
    i.e. the DNA or RNA comprising its genetic material, so as
    to form an identical genome. This is an essential step in
    the division of one cell into two. This differs from
    {transcription}, which is the copying of only part of the
    genetic information of a cell's genome into RNA, as in the
    processes of biosynthesis of messenger RNA or ribosomal
    RNA.

    11. The team hasn't yet published its recipe for making the new molecule, which may delay replication of the results by other scientists.
