PPT-Lecture 3 What is Mutation?

Is a natural process that changes a DNA sequence Mutant or Mutation to describe something undesirable or broken Rarely cause death or disease Generates new variations that can give an individual a survival advantage. 30pm 730pm 730pm 730pm Hold Your Applause Inventing and Reinventing the C lassical Concert Hold Your Applause Inventing and Reinventing the C lassical Concert Hold Your Applause Inventing and Reinventing the C lassical Concert Hold Your Applause I Jesus.

A . frameshift. mutation – . a point mutation due to an addition . or deletion of a DNA base that causes a major change in the genetic code.. 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 .
