POLK

POLK (DNA Polymerase Kappa): POLK, a member of the Y-family DNA polymerases, is crucial for translesion DNA synthesis, a process that allows DNA replication to continue past DNA lesions such as UV-induced pyrimidine dimers or bulky chemical adducts. It plays a specialized role in accurately replicating damaged DNA, thereby preventing the stalling of replication forks and the formation of potentially mutagenic double-strand breaks. POLK's unique ability to replicate through lesions that would otherwise stall replicative polymerases ensures genome stability and integrity. However, its error-prone nature can also lead to mutagenesis, making it a double-edged sword in DNA repair processes. Dysregulation...

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the UK. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
