Get inspiration for Chromosome Powerpoint Template. General Chromosome Model: This model was proposed by Crick in 1971; it suggests that DNA in a chromatid is a large monomer which runs continuously from one end to the other. The two steps leading to repair are the formation of a synapsed state between one of the donor loci (HML or HMR) and MAT and the repair of the DNA … Also can be used at classroom in subjects related to Genetics or Bioinformatic presentations.
