Mutations involving changes in the nucleotide
Reviewed by: Mary Anne Clark, Ph.D.
This page is a continuation of the previous tutorial, Chromosome Mutations – I.
The previous examples of mutation have investigated changes at the chromosome level. The sequence of nucleotides on a DNA sequence are also susceptible to mutation.
All of the genetic mutations looked at through the last 2 pages more or less have a negative impact and are undesired, however, in some cases they can prove advantageous.
Genetic mutations increase genetic diversity and therefore have an important part to play. They are also the reason many people inherit diseases.
The next tutorial looks at the mutation at the gene level.
