CUET Preparation Today
| Two DNA samples A and B have melting temperatures 305K and 320K respectively. Identify the correct statement based on this information. |
A has more hydrogen bonds than B A has more CG pairs than B
B has more CG pairs than A
A and B are complementary strands
|
| B has more CG pairs than A |
| CG bonds are made of triple hydrogen bonds and AT bonds are made of double hydrogen bonds. Since the melting temperature of B is higher than that of A, B should have more hydrogen bonds and as a result more CG pairs |
