  • A mutation is a permanent change in the DNA sequence of a gene. Sometimes mutations in DNA can cause changes in the way a cell behaves. This is because genes contain the instructions necessary for a cell to work. If some of the instructions to the cell are wrong, then the cell may not know what it is supposed to do. There are two ways in which DNA can become mutated: 1.) Mutations can be inherited. This means that if a parent has a mutation in his or her DNA, then the mutation is passed on to his or her children. 2.) Mutations can be acquired. This happens when environmental agents damage DNA, or when mistakes occur when a cell copies its DNA prior to cell division.
  • Drinking and the intake of illegal substances while pregnant can attribute to mutations
  • Mutations happen for several reasons. 1. DNA fails to copy accurately. Most of the mutations that we think matter to evolution are “naturally-occurring.” For example, when a cell divides, it makes a copy of its DNA—and sometimes the copy is not quite perfect. That small difference from the original DNA sequence is a mutation. 2. External influences can create mutations. Mutations can also be caused by exposure to specific chemicals or radiation. These agents cause the DNA to break down. This is not necessarily unnatural—even in the most isolated and pristine environments, DNA breaks down. Nevertheless, when the cell repairs the DNA, it might not do a perfect job of the repair. So the cell would end up with DNA slightly different than the original DNA and hence, a mutation. http://evolution.berkeley.edu/evosite/evo101/IIIC3Causes.shtml
  • exposure to certain toxic chemicals. I'm sure radiation wouldn't help either.
  • Free radicals can attenuate the alleles and when the cells undergo mitosis, this may have unexpected new developments when the cells undergo cell division, including the genes so that when humans copulate their offspring will acquire these mutations and hence be different in ways far radical than their progenitors. Also if I were to substitute the phrase 'free radical' with recessive / dominant genes in a more conventional sense the off spring will therefore inherit the genes which have won the battle of dominance / submissive dominance but this doesn't explain mutation though. Refer to the first part of my answer.
  • drunk evolutionists
  • a lot of things most commonly reproduction. Everytime a species reproduces the DNA mutates slightly.
  • Inbreeding, dieseses some more
  • In normal cases chemicals and radiations could make DNA mutation But Viruses and some bacteria are able to make genetic mutations because they have very short lifecycle .. I hope thus is help!
