A segment of DNA/RNA molecule that contains information of coding for a protein or peptide sequence is known as
Answer: D
The coding segment is called an exon.
In eukaryotic genes, the sequence is divided into exons, which are expressed and carry the information that is translated into the protein, and introns, which are non-coding sequences removed from the RNA by splicing before translation.
An intron is therefore the non-coding part. A codon is just one triplet of three bases coding for a single amino acid, not a whole coding segment. A muton is the smallest unit of DNA in which a mutation can occur (Benzer's term).
