Question

Which of the following sequences would pair best with 5'-AGCTTAGC-3?

a. 5'-TCGAATCG-3'
b. 5'-UCGAAUCG-3'
c. 5'-AGCTTAGC-3'
d. 5'-GCUAAGCU-3'

Answer 1

. 5'-TCGAATCG-3'

Step-by-step explanation:

Deoxyribonucleic acid consist of 2 Nitrogenous bases that pairs up during DNA formation.

We have purines and pyrimidine

Purine include Adenine and Guanine

Pyrimidine include Thymine and Cytosine

During base pairing, Adenine pairs with Thyamine and Guanine pairs Cytosine except in Ribonucleic acid where Uracil replaces Thymine.

Therefore the best pair is

5'-AGCTTAGC-3

. 5'-TCGAATCG-3'
