Question

Okazaki fragments are formed during which process?

• A. Transcription
• B. Translation
• C. DNA replication
• D. None

Hint:

Think about the discontinuous lagging strand of DNA.

Answer 1

The Correct Option is C

Step 1: The key fact to recall is that Okazaki fragments belong to the lagging strand of DNA, so the event in question must be DNA copying, not RNA or protein making.

Step 2: Because the two DNA strands are antiparallel and the enzyme works only 5' to 3', one template strand is read smoothly (leading) while the other is read in short back-stitched segments (lagging). Those short segments carry the name Okazaki.

Step 3: Each fragment starts with an RNA primer laid by primase, is extended by DNA polymerase, and the pieces are finally sealed by ligase into one strand.

Step 4: Transcription and translation involve RNA and protein synthesis respectively and never produce these DNA segments, so option d is also excluded.

\[\boxed{\text{DNA replication}}\]
