im not exactly sure what you are looking for when you say "events on which mutation can occur," but i will take a shot at answering.

exposure to UV light is one cause of genetic mutation. your DNA consists of pairs of A-T and G-C (Adenine-Thymine, Gaunine-Cytosine), called "base pairs." when in your DNA there are two T's side by side on one strand, exposure to UV light can cause them to bind together, creating a Thymine dimer. this can cause problems later, when genes need to be transcribed or replicated.

another example of an event which sometimes causes mutation in developing babies is something called nondisjunction. when a cell undergoes meiosis (reproduction) the cell has to copy its DNA, then line up the copies in condensed chromosomes and split them apart so each new daughter cell gets half of the DNA. sometimes however, a mistake is made and paired chromosomes do not disjoin correctly, giving all genetic information from one chromosome pair to only one of the cells. this results in several "odd" physical expressions, including down's syndrome.

there are many, many mutations which occur in eukaryotic cells commonly, and for many reasons. we undergo mutations ourselves on a near daily basis (for 1 in 4 people this unfortunately will result in cancer with time), they are simply not noticed by us because our amazing bodies have ways of coping with them, and because we have many portions of noncoding DNA (introns) insterted randomly in our genetic code which makes mutation of significant genes much less likely. I would suggest asking a doctor, biology teacher, or consulting a textbook for further information.
