How does dna mutation occur
WebOct 13, 2010 · Each strand is then copied to become another double strand. About 1 out of every 100,000,000 times, a mistake occurs during copying, which can lead to a mutation. We can certainly take comfort in that statistic, as well as the fact that our DNA does a stand-up job of repairing itself when mutations occur [source: Learn. Genetics. WebA deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand (Figure 3).
