Detailed explanation-1: -The sections of DNA (or RNA) that code for proteins are called exons. Following transcription, new, immature strands of messenger RNA, called pre-mRNA, may contain both introns and exons.
Detailed explanation-2: -Exons are coding sections of an RNA transcript, or the DNA encoding it, that are translated into protein. Exons can be separated by intervening sections of DNA that do not code for proteins, known as introns.
Detailed explanation-3: -An exon is a region of the genome that ends up within an mRNA molecule. Some exons are coding, in that they contain information for making a protein, whereas others are non-coding. Genes in the genome consist of exons and introns.
Detailed explanation-4: -The coding region of a gene, also known as the coding sequence (CDS), is the portion of a gene’s DNA or RNA that codes for protein.
Detailed explanation-5: -The protein coding sequences for many genes are broken into smaller pieces of coding sequences called exons separated by non-coding sequences called introns. When genes are transcribed, those exons and introns are included in the initial messenger RNA products.
