Segments of lagging strand formed during DNA synthesis are

Options

A. Polymerase fragment
B. RNA fragment
C. Okazaki fragments
D. Epimerase activity

Answer

To answer the question regarding the segments of the lagging strand formed during DNA synthesis, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding DNA Replication**: DNA replication occurs in two directions on the double-stranded DNA molecule. The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments.

2. **Lagging Strand Synthesis**: The lagging strand is synthesized in the opposite direction to the replication fork movement. This means it is synthesized discontinuously.

3. **Formation of Short Segments**: During the synthesis of the lagging strand, short segments of DNA are formed. These segments are necessary because DNA polymerase can only add nucleotides in the 5' to 3' direction.

4. **Okazaki Fragments**: The short segments formed on the lagging strand during DNA synthesis are known as Okazaki fragments. Each fragment is initiated by a short RNA primer, which is later replaced by DNA.

5. **Conclusion**: Therefore, the segments of the lagging strand formed during DNA synthesis are called Okazaki fragments.

### Final Answer:
The segments of the lagging strand formed during DNA synthesis are Okazaki fragments.
