PPT-Unit 2 What is Mutation?

Is a natural process that changes a DNA sequence As a cell copies its DNA before dividing a typo occurs every 100000 or so nucleotides Thats about 120000 typos each time one of our cells divides.

Mutation refers to sudden heritable change in the phenotype of an individual. In the molecular term, mutation is defined as the permanent and relatively rare change in the number or sequence of nucleotides. In other words, mutations arise due to change in DNA bases. The change in the nucleotide may involve replacement of one . Is a natural process that changes a DNA sequence.. Mutant or Mutation – to describe something undesirable or broken..
