Anything beneficial to wrong nucleotide placement in DNA

Post by NewtoBiology » Tue Aug 18, 2009 10:13 pm

Hello biologists,

I have just finished a chapter on DNA replication and the proof reading it engages in. I also studied about the different types proof reading the cell engages in to make sure that the DNA is correct. HOWEVER, despite the numerous checks present in the cell to prevent the placement of wrong nucleotides, is there anything BENEFICIAL to this in the long run?

This is not a homework question, but I am simply just asking for my own self.
Could some base errors lead to evolutionary adaptations, that would have otherwise been unheard of?

Any feed back would be greatly appreciated!

Well mutations are definitely a way to create genetic diversity, yes. One could wrote a PhD thesis on the subject, or more (as I and many friend from the laab I studied did).
An example of what happens in bacteria here.

Good luck researching the vast subject.
