All of the following is transcribed from DNA except

Answer: Option B

All of the following is transcribed from DNA except Exons.
Exons are the sequence of DNA present in mature messenger RNA, some of which encode the amino acids of a protein.
these are coding sections of an RNA transcript, or the DNA encoding it, that is translated into protein.
Exons can be separated by intervening sections of DNA that do not code for proteins, known as introns.
