DNA Replication

Front

What is DNA replication?

Back

The process by which a cell makes an identical copy of its DNA, resulting in two new DNA molecules.

Front

What is a replication fork?

Back

The Y-shaped region where the DNA double helix separates during replication.

Front

What do 3' and 5' refer to in DNA?

Back

They refer to the directionality of the DNA strands, indicating the carbon numbers in the DNA's sugar backbone.

Front

In which direction does DNA replication occur?

Back

DNA replication occurs from the 5' end to the 3' end.

Front

What is the leading strand in DNA replication?

Back

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

Front

What is the lagging strand in DNA replication?

Back

The strand that is synthesized discontinuously in short segments, opposite to the direction of the replication fork.

Front

What are Okazaki fragments?

Back

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

Front

What role does helicase play in DNA replication?

Back

Helicase is the enzyme that unwinds and separates the DNA strands at the replication fork.

Front

What is the function of DNA polymerase?

Back

DNA polymerase is the enzyme that adds nucleotides to the growing DNA strand during replication.

Front

What is the significance of the RNA primer in DNA replication?

Back

The RNA primer provides a starting point for DNA polymerase to begin synthesis.
