Detailed explanation-1: -Definition. 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.
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: -The coding region (also called coding sequence, or CDS), is the portion of the mRNA that is actually translated into protein. The mRNA also includes an untranslated region on each end, called the 5’ UTR and 3’ UTR.
Detailed explanation-4: -The mRNA interacts with a specialized complex called a ribosome, which “reads” the sequence of mRNA nucleotides. Each sequence of three nucleotides, called a codon, usually codes for one particular amino acid. (Amino acids are the building blocks of proteins.)
Detailed explanation-5: -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.
