A gene mutation is a permanent change in the DNA sequence, that makes up a gene. Mutations range in size, from a single DNA building block (DNA base), to a large segment of a chromosome.enetic mutations are not always harmful. A lot of mutations have a positive effect on the host. Some genetic mutations may help the host endure certain conditions in the envi â¦ ronment, or eat certain food, or resist a certain superbug or virus, etc etc. However, some mutations can be harmful.
  A mutation is a permanent change in the DNA sequence of a gene.   There are two ways in which a DNA mutation can occur:   1) Mutations can be inherited.This means â¦ 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.or example, this can happen during crossover during the formation of gametes. Substitution mutations happen when one nucleotide (the smallest unit of DNA) is replaced by another. These are caused by a number of chemicals that look like something in between both of those nucleotides.
