Front

What is the role of DNA polymerase in DNA replication?

Back

Adds new nucleotides to the growing DNA strand.

Front

What is the function of ligase in DNA replication?

Back

Joins Okazaki fragments on the lagging strand.

Front

What are Okazaki fragments?

Back

Short sequences of DNA synthesized on the lagging strand during DNA replication.

Front

What is the significance of the 5' to 3' direction in DNA replication?

Back

DNA strands are synthesized in the 5' to 3' direction, meaning nucleotides are added to the 3' end.

Front

What is the difference between leading and lagging strands?

Back

Leading strand is synthesized continuously, while lagging strand is synthesized in short fragments.
