Solution

The correct option is D Polymerize in the 5' to 3' direction and explain 3' to 5' DNA replication
Okazaki fragments are the newly synthesized DNA fragments formed on the lagging template strand (one that replicates discontinuously) of DNA during replication. These are in fact short double-stranded DNA sections which polymerize in the 5' to 3' direction and explains the 3'to 5' replication of DNA.
So, the correct answer is 'Polymerize in the 5' to 3' direction and explain 3' to 5' DNA replication'
