How positive super coils are released?

Explanation

**Step-by-Step Solution:**

1. **Understanding Supercoiling:**
- During DNA replication, the double helix structure of DNA unwinds to allow the replication machinery to access the strands. This unwinding creates tension in the DNA, leading to the formation of positive supercoils ahead of the replication fork.

**Hint:** Consider how unwinding a tightly coiled rope creates twists and tension in the remaining sections.

2. **Role of Topoisomerase:**
