DNA Replication

Front

What is DNA replication?

Back

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

Front

What is the shape of DNA?

Back

Double helix.

Front

What enzyme unwinds the DNA double helix during replication?

Back

Helicase.

Front

What is the role of DNA polymerase?

Back

To add free nucleotides to the growing DNA strand during replication.

Front

What is the function of primase in DNA replication?

Back

To synthesize short RNA primers that provide a starting point for DNA synthesis.

Front

What is the significance of the leading and lagging strands in DNA replication?

Back

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

Front

What are Okazaki fragments?

Back

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

Front

What is the role of ligase in DNA replication?

Back

To join Okazaki fragments together on the lagging strand.

Front

What happens to the hydrogen bonds between base pairs during DNA replication?

Back

They are broken to allow the strands to separate.

Front

What is the end result of DNA replication?

Back

Two identical DNA molecules, each consisting of one original strand and one newly synthesized strand.
