Question

do cistron,inton and exon have some specifc structure?

Answer 1

Yes cistron, exons and introns are polynucleotides having a particular structure. Cistron (other name for gene) is the segment of DNA that codes for a particular polypeptide. While exons and introns are two parts of a gene in which exon codes for a particular character and introns are the interrupting sequences in a gene that are recognized and spliced out from RNA transcript.
