Mutation
... DNA can give rise to one of nine other codons. Two of the possible changes (CUA , UUG) are completely silent, as the resulting codons still code for leucine. These are known as synonymous codons. Two further changes (AUA and GUA) may well have little effect on the protein since the substituted amino ...

A polynucleotide has a free phosphate group at one end, called the 5' end because the phosphate is attached to carbon 5' of the sugar, and a free OH group at the other end, called the 3' end because it's on carbon 3' of the sugar. The terms 3' and 5' are often used to denote the different ends of a ...
