Describe the fate of each strand of donor dsDNA during homologous recombination
Describe the fate of each strand of donor dsDNA during homologous recombination
Homework Answers
Answer:- During homologous recombination ,one of two sister chromatids of the identical homologous chromosomes exchanged their part with one another as a result both the ds DNA become recombinant and they seems genetical variation from original strand. This homologous revombination are helpful in DNA damage and are helpful in creating recombinant organism.

Homologous Recombination A. How are the repair of double strand breaks (DSBs) and production of DSBs for recombination connected? B. How does the general model of strand invasion, branch migration, and resolution of the Holliday junction work? C. How do RecA and RecBCD function to promote recombination? D. Endonuclease activity of RecBCD is greater in the 3'-5' strand, rather than the 5'-3' strand. Describe how this affects strand invasion, branch migration and resolution. E. How is recombination initiated during meiosis...

Haploid yeast cells that preferentially repair double-strand breaks by homologous recombination (rather than by non-homologous end joining) are especially sensitive to agents that cause double-strand breaks in DNA. If the breaks occur in the G1 phase of the cell cycle, most cells will die; however, if the breaks occur in the G2 phase, a much higher fraction of cells survive. Why do you suppose this is?
