MCQ
Which of the following is not present in nucleic acids
- AUracil
- ✓$2$ - aminopyridine
- CThymine
- DAdenine
✓
Answer
Correct option: B.
$2$ - aminopyridine
b
$2-$aminopyridine is not present in nucleic acid and as cytosine, Adenine, Thymine and $GUANINE$ are the four main bases found in nucleic acid. Adenine and Guanine are purines while thymine and cytosine are pyrimidines. They together form triple bonded histones of $DNA$.$2-$Aminopyridine is an organic compound with the formula $H _2 NC _5 H _4 N$. It is one of three isomeric aminopyridines
