Front

What is the role of DNA polymerase in replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the function of ligase in DNA replication?

Back

Ligase joins Okazaki fragments on the lagging strand, sealing nicks in the sugar-phosphate backbone.

Front

What are the three main steps of DNA replication?

Back

1. Initiation, 2. Elongation, 3. Termination.

Front

What is the significance of the semi-conservative nature of DNA replication?

Back

Each new DNA molecule consists of one original strand and one newly synthesized strand, ensuring genetic continuity.

Front

What is the difference between leading and lagging strands during DNA replication?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments called Okazaki fragments.
