Solution
The correct option is C Assertion is correct but Reason is incorrect
The portion of a gene in DNA or RNA, composed of exons, that codes for the proteins. It is also called as coding region of the DNA.There are three common technical terms in molecular genetics, exon, intron, and codon. Exons and introns are features of DNA, whereas codons are features of RNA. Exon is a part of a gene that encodes a part of the final mature RNA produced by that gene after introns have been removed by RNA splicing.Introns are called intervening sequences in any nucleotide sequence within a gene that is removed by RNA splicing during maturation of the final RNA product. Thus, the correct answer is option C.
