The portion of the eukaryotic genes which are not a part of mature mRNA:
Open in App
Solution
The correct option is A Introns
Introns are DNA segments that lie between successive coding (exons) regions in the gene. Introns are transcribed along with the exons but they are spliced out during RNA processing.
The exons are that part of the gene which is present in the mature mRNA and translated into a polypeptide.
Codons are a triplet of nucleotides that specifies a particular amino acid. There are sixty-one codons that specify an amino acid and are used in forming proteins. Three stop codons do not specify any amino acid.
Cistron is that segment of DNA that codes for a polypeptide and is defined by a genetic test as a region within which two mutations cannot complement each other.
