Question:- What is the portion of DNA that codes for a particular protein called?

Answer: It is called a gene.

A genome refers to a set of all hereditary information for synthesizing functional necessities, usually in the shape of a protein within an extended chain of DNA molecules. It acts as the smallest working biological structure as it contains all the genetic data associated with the synthesis of particular proteins that are essential for the normal functioning of an organism. Genes therefore contain exons which are the areas of DNA that contain instructions to produce a particular protein and introns which are non-coding areas of DNA which are eventually cut out during splicing. mRNA molecule holding the exon sequences is again transcribed by ribosome into a certain string of amino acids which forms a functional protein. They work in pairs to determine the particular traits of an organism and ensure every complex biochemical process in all living organisms.
