What do A and G of one strand of DNA compulsorily base pair with?
Options
- AA and T respectively, on the other strand.
- BT and C respectively, on the other strand.
- CC and G respectively, on the other strand.
- DA and C respectively, on the other strand.
Correct answer
B. T and C respectively, on the other strand.
Step-by-step solution
The heterocyclic compounds in nucleic acids are the nitrogenous bases named adenine, guanine, uracil, cytosine, and thymine. Adenine and Guanine are substituted purines while the rest are substituted pyrimidines. The skeletal heterocyclic ring is called as purine and pyrimidine respectively. A and G of one strand of DNA compulsorily base pair with T and C, respectively, on the other strand .
