Front

What is the fifth step in DNA replication?

Back

Ligase glues together the fragments on the lagging strand of DNA.

Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA.

Front

What role does helicase play in DNA replication?

Back

Helicase unwinds the DNA double helix by breaking the hydrogen bonds between the bases.

Front

What is the function of primase in DNA replication?

Back

Primase synthesizes a short RNA primer to provide a starting point for DNA synthesis.

Front

What is the leading strand in DNA replication?

Back

The leading strand is the DNA strand that is synthesized continuously in the same direction as the replication fork.

Front

What is the lagging strand in DNA replication?

Back

The lagging strand is synthesized in short segments called Okazaki fragments, in the opposite direction of the replication fork.
