What is Mutation?

• Mutation refers to a permanent alteration in the DNA sequence of a gene or chromosome. This change can occur due to intrinsic factors, such as errors during DNA replication, or extrinsic factors, including exposure to environmental elements like UV light.

  Essentially, a mutation involves a modification in the nucleotide sequence of DNA.

• The significance of mutation lies in its role in biological processes.
  What is mutation in biology

  Mutations can be beneficial, detrimental, or neutral, depending on their nature and context. They are a crucial driver of genetic diversity and evolution, as they introduce new alleles into populations, thereby contributing to the adaptation and survival of species.

• The concept of mutation has its roots in the Latin word “mutare,” which means “to change.” The term itself was introduced by the Dutch botanist Hugo de Vries in 1890.

  However, the phenomenon of mutation was first observed by Seth Wright, an English farmer, in 1791 through unusual short-legged lambs. Wright, though, did not formally define the process.
