Question

Which of the following is not true for mRNA?

• A. Chargaff’s rule
• B. RNA is unstable and degradable
• C. Complementary base pairing
• D. 5’ phosphoryl end and 3’ hydroxyl end

Answer 1

The correct option is A Chargaff’s rule

Chargaff determined that in any double-stranded DNA the number of guanine units equals approximately the the number of cytosine units and the number of adenine units equals approximately the number of thymine units. mRNA is single stranded, So Chargaff's rule is not true to mRNA.
