Mutations

ID #1245

I wrote down something really quickly about a Error Prone or SOS Repair mechanism. What exactly is this?


There are times when damage to DNA is so significant that a replication fork cannot pass. Obviously if no action is taken, the cell will not be able to divide. So the cell will call its repair systems into action, trying first to fix the problem without introducing any mutations. But sometimes this isn't possible, and the repair system itself introduces mutations in the genome. It patches the DNA back together, so you survive, but now you've got one or more mutations. Taking your chances with a mutation is better than certain death, and this is called "error prone" repair.
