what is a DNA mutation ?

what increases the likely hood of mutations ?
carcinogens
Ionising radiation
what is a gene ?
a section of DNA that codes for a particular amino acid
effects of mutations ?
amino acid codons code for change meaning the sequence of amino acids change so they would make a different protein meaning it changes shape or function eg changes active site of enzymes

substitution
insertion
