Impact of Mutations on Enzyme Activity

In the context of molecular biology, proteins play crucial roles in various cellular functions and processes. Proteins are synthesized from amino acids, and the sequence in which these amino acids are arranged is determined by the genetic code. A specific region of DNA, known as the coding sequence, is transcribed into messenger RNA (mRNA) and subsequently translated into a polypeptide chain forming a protein. Mutations in the coding sequence can lead to changes in the protein produced, potentially resulting in altered function or loss of function.

Consider an experiment where a certain mutation occurs within the coding sequence of a gene responsible for producing an important enzyme. This mutation results in a single amino acid being replaced in the enzyme's structure. Researchers want to determine how this mutation impacts the enzyme's activity.
