Definition of semi-conservative in English:



  • Relating to or denoting replication of a nucleic acid in which one complete strand of each double helix is directly derived from the parent molecule.

    • ‘In contrast to the semi-conservative process of DNA replication where both strands are synthesized simultaneously, only one strand of the DNA is copied during RNA transcription.’
    • ‘The ends of the invading strands serve as primers for semi-conservative repair synthesis (mostly short tracks of a few kilobases) so that one newly synthesized strand is present in each of the donor and recipient.’
