Question

How can we identify that that cell want dna repair researchgate?

Answer 1

There are many methods for detecting DNA damage. The one you use depends on the type of DNA damage that you want to measure. For example the gamma H2AX assay is used to detect DNA double strand breaks  whereas the comet assays are used to detect both single and double strand breaks. There are also assays that can be used to identify which repair pathway a cell is using to repair the damage. If you can provide more details on the experiment you are doing I will be able to be more specific!
