A parenchymatous cell has 20 units of DNA It starts to divide mitotically: How many units of DNA would it have: (a) during late prophase, (b) during anaphase, and (c) during very late telophase.

Explanation

To solve the question regarding the number of DNA units in a parenchymatous cell during different stages of mitosis, we can break it down step by step.

### Step-by-Step Solution:

1. **Understanding the Initial Condition:**
- The parenchymatous cell starts with **20 units of DNA**. This is the diploid number (2n), meaning that it has two sets of chromosomes.

**Hint:** Remember that the total DNA content is doubled during the S phase of the cell cycle before mitosis begins.
