Ward AP Biology: DNA Replication

Front

What is the purpose of DNA replication?

Back

To create two identical molecules of DNA.

Front

What enzyme creates a primer to begin a new strand of DNA in DNA replication?

Back

RNA Polymerase.

Front

Which strand is synthesized continuously during DNA replication?

Back

Leading strand.

Front

Which enzyme joins fragments of the lagging strand?

Back

Ligase.

Front

What direction does DNA polymerase move when creating the leading strand?

Back

Toward the replication fork.

Front

What is the lagging strand?

Back

The strand that is synthesized in short segments away from the replication fork.

Front

What is the role of helicase in DNA replication?

Back

To unwind the DNA double helix.

Front

What are Okazaki fragments?

Back

Short segments of DNA synthesized on the lagging strand.

Front

What is the function of DNA polymerase?

Back

To synthesize new DNA strands by adding nucleotides.

Front

What is the significance of complementary base pairing in DNA replication?

Back

It ensures that the new DNA strands are accurate copies of the original.
