What is a mutation? How does this change the information in a DNA molecule?
Since this is not my area of expertise, I searched Google under the key words "mutation DNA" to get these possible sources:
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
What is a mutation?
a mutation is a change of a nucleotide sequence (AGTGCCATAA etc.) of the genome of an organism.
How does this change the information in a DNA molecule?
It changed the order of the nucleotide sequence. I.e. if you had a CTG sequence that codes for a protein that makes you blue and a mutation comes and changed it to CGT, you'll turn green.
