What are called Okazaki fragments ?

Explanation

**Step-by-Step Solution:**

1. **Understanding DNA Replication**: DNA replication is the process by which a cell duplicates its DNA before cell division. This ensures that each new cell receives an exact copy of the DNA.

2. **Leading and Lagging Strands**: During DNA replication, two strands of DNA are involved. One strand is synthesized continuously in the direction of the replication fork, known as the **leading strand**. The other strand, however, is synthesized in a discontinuous manner.

3. **Formation of Okazaki Fragments**: The strand that is synthesized discontinuously is called the **lagging strand**. On this lagging strand, DNA is synthesized in small segments or fragments. These small segments are known as **Okazaki fragments**.
