The sequence of N-bases in one strand of DNA is '3 TAC CAC TCC ATA ATT 5'. How many purines will be present in the Watson crick structure of this DNA?
Options:
Answer:
C
Solution:
A purine is an aromatic heterocycle composed of carbon and nitrogen. Purines include adenine and guanine, which participate in DNA and RNA formation. Purine is a heterocyclic aromatic organic compound that consists of a pyrimidine ring fused to an imidazole ring.
According to the Watson–Crick model of DNA, DNA is double-stranded.
The given sequence of a DNA strand is:
3' TAC CAC TCC ATA ATT 5'
5' ATG GTG AGG TAT TAA 5'
