Detailed explanation-1: -Introns are noncoding sections of an RNA transcript, or the DNA encoding it, that are spliced out before the RNA molecule is translated into a protein.
Detailed explanation-2: -An intron is a region that resides within a gene but does not remain in the final mature mRNA molecule following transcription of that gene and does not code for amino acids that make up the protein encoded by that gene.
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 Beginning of mRNA Is Not Translated This portion of mRNA is located between the first nucleotide that is transcribed and the start codon (AUG) of the coding region, and it does not affect the sequence of amino acids in a protein (Figure 3).
Detailed explanation-5: -Introns, particularly first introns, have important roles in the correct cytoplasmic localization of some mRNAs, including the Drosophila oskar gene and mRNA export [60, 65] as well as in transcriptional and translational regulation [61, 66, 67].
