What is recombinant DNA? How do we cut and paste DNA
Genetic recombination occurs when blocks of genes from homologous chromosomes are 'switched' by the process of crossing over. During the process of reciprocal recombination:
1. 2 DNA duplex molecules are broken (cut)
2. Broken DNA strands are exchanged, or 'swaped'
3. DNA strands are re-ligated ...
