Such mechanisms not only make sure every important event in the cycle takes place adequately (e.g. DNA replication, chromosome segregation) but also repair any damage associated with ...

Then you separate out this mix with a series of steps of washing, spinning down with a centrifuge, and extraction. A DNA extraction kit is involved. Here'...
