Ionizing radiation is damaging to DNA, but is there such a thing as a safe dose below which no DNA damage could occur? I'm not asking about a minimum safe dose overall, just whether or not there's an ...
As far as I know, the DNA sequence becomes shorter every time a cell divides. A shorter sequence results in information loss and aging characteristics. As a countermeasure, shouldn't one stay young ...
Is it possible for cells from the same tumor to have different genetic material, and if so, to what degree is it possible (how fast do they mutate) ?
I want to use the method of Single Cell Gel Electrophoresis (comet assay). I have many samples, but I don't have the appropriate microscope. So I have to preserve my slides until the time comes for ...
What is the strict difference between mutation and DNA damage? As far as I understand it, a mutation is an alteration in the genetic sequence, having "tricked" the repairing machinery and thus ...
Mitochondria are considered endosymbionts originated from a prokaryote. So, do they have a DNA repair mechanism ?
