Question

The functional unit of DNA molecule that codes for particular gene product is

• A. Cistron
• B. Exon
• C. Intron
• D. Gene

Answer 1

The correct option is A Cistron

Cistron is the functional unit of the DNA that encodes for the translation. The codons on the DNA in the region of cistron helps in the synthesis of proteins by the process of translation. The mRNA which encodes for the single polypeptide is known as monocistronic while those who synthesize for the number of polypeptides is known as polycistronic.

So, the correct answer is option A.
