Degeneracy

Degeneracy

(Science: molecular biology) The coding of a single amino acid by more than one base triplet (codon).

Of the 64 possible codons, three are used for stop signals, leaving 61 for only 20 amino acids. Since all codons can be assigned to amino acids, it is clear that many amino acids must be coded by several different codons, in some cases as many as six.

Re: Theories - Origin of Life

... is that multiple analogous adaptations pose a problem for Darwinian theory. As I mentioned above, natural selection has no bias with respect to degeneracy. If it works, it works. I believe that over long periods of time, which is what Darwinian theory is partly based on, it would be possible ...

degeneracy of genetic code

Thanks god or whoever did it, for the degeneracy of the genetic code :lol: I'm just looking for my sequenced plasmids and there is lot of mess, so I was really lucky to find at least one clone, which is OK. Except of a single mutation... which ...

How often do mutations occur?

... the question is, whether they are repired or not ;) If they are not (like in 1.10^9 cases approx), than in most cases they have no effect (see the degeneracy of the genetic code) and if they change something, it's usually into some similar aminoacid actually. But anyway, there are two schools regarding ...

The term "degeneracy of genetic code"

Hi, well, I haven't think about that in this way anytime earlier :) But if you look e.g. here: http://www.answers.com/topic/degeneracy there is also meaning "declination, decline, decay, deterioration" and its antonyms: development, improvement. This is, in my opinion, meaning ...
