How do DNA mutations occur? (3) - Answer-a mutation is any random change in the chemical structure of DNA 1) as a consequence of exposure to chemicals or UV light 2) at random bc of the chemical structure of the DNA 3) as a consequence of the activity of some cellular enzymes that induce the loss of specific chemical groups whats a silent mutaation? (aka neutral mutation) - Answer-changes in the nucleotide sequence of genomic DNA that have no effect on the type of genetic info encoded i...
