Substitution Mutation

Substitution mutation is the process by which one nucleotide in a DNA sequence is substituted with a different one. It is an important form of molecular evolution in which the genetic code of organisms changes over time, leading to new and novel genetic combinations. Substitution mutation can lead to the generation of new alleles and the evolution of novel traits. It is also used in genetic engineering and biotechnology to produce organisms with improved traits. Therefore, substitution mutation plays an important role in evolution and biotechnology.
