This model suggests that this sugar plug can also begin the signal for apoptosis. It is highly expressed during mitosis and elevated levels are found in many different types of cancer. Rad51 family members are highly similar to bacterial reca and saccharomyces cerevisiae rad51 and are known to be involved in the homologous recombination and repair of dna.

Chromothripsis is a mutational process by which up to thousands of clustered chromosomal rearrangements occur in a single event in localised and confined genomic regions in one or a few chromosomes and is known to be involved in both cancer and congenital diseases it occurs through one massive genomic rearrangement during a single catastrophic event in the cell s history. The dna binding domain prevents other non cleaved parp from accessing the damaged site and initiating repairs.
