The number of cytosine bases in a DNA molecule is equal to the number of ............. bases.

Explanation

To solve the question, "The number of cytosine bases in a DNA molecule is equal to the number of ............. bases," we can follow these steps:

### Step-by-Step Solution:

1. **Understand DNA Structure**: DNA is composed of four types of nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).

2. **Base Pairing Rules**: In DNA, the bases pair specifically: adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G). This means that for every cytosine base, there is a corresponding guanine base.
