DNA Replication
... DNA does not copy itself. Enzymes and other proteins do the actual work of replication. Here we will look at the process of replication in eukaryotes. The process is similar in prokaryotes. First, some enzymes pull apart, or unzip, the double helix to separate the two strands of DNA. Other proteins ...

Effects of mutations
... • When a base is substituted in DNA the mutation may have 2 effects: – Changes the amino acid – Does not change the amino acid – Why doesn’t a mutation always change the amino acid sequence? Because the genetic code is degenerate and has amino acids that may be coded for by different codons. (I.e., ...

Mutagen
In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, mutagens are therefore also likely to be carcinogens. Not all mutations are caused by mutagens: so-called ""spontaneous mutations"" occur due to spontaneous hydrolysis, errors in DNA replication, repair and recombination.
