A DNA molecule with more number of GC base pairs than AT base pairs has higher `T_(m)` than the one with lesser number of GC base pairs than AT base pairs. Explain why?

Explanation

To explain why a DNA molecule with a higher number of GC base pairs has a higher melting temperature (T_m) than one with more AT base pairs, we can break down the reasoning into several steps:

### Step-by-Step Solution:

1. **Understanding DNA Structure**:
- DNA is composed of four nitrogenous bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).
- These bases pair specifically: A pairs with T (forming an AT base pair), and G pairs with C (forming a GC base pair).
