What is Mutation?
Definition: Any change in the DNA sequence in the cell is known as mutation.
These alterations can occur due to faults in DNA replication, exposure to radiation or toxins, or spontaneous variations occurring over time. The consequences of significant DNA segment deletions and rearrangements are simple to understand. It might cause a gene to lose or gain function. Example: The modification of a single base pair in the gene encoding the beta globin chain, which causes the amino acid residue glutamate to change to valine, is a typical case of a point mutation.
Genetic Code and Mutations
Genetic code and mutations are important to understand and explain the central dogma of biology. The set of rules governing how DNA sequences are translated into proteins is the genetic code. The four nucleotide bases adenine (A), thymine (T), guanine (G), and cytosine (C), which are organized in particular sequences to produce genes, make up the genetic code.
Mutations are of different types based on what kind of changes occur in the genetic sequence. An amino acid sequence in a protein is determined by the nucleotide sequence in a gene. In this article, we will cover the genetic code and mutations.
