DNA Replication

Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA, ensuring that each new cell receives a complete set of genetic information.

Front

What is the role of DNA Polymerase?

Back

DNA Polymerase is the enzyme responsible for synthesizing new DNA strands by adding nucleotides to a growing chain during DNA replication.

Front

In which direction is the new DNA synthesized on the leading strand?

Back

The new DNA on the leading strand is synthesized in the 5' to 3' direction.

Front

What are Okazaki fragments?

Back

Short segments of DNA synthesized on the lagging strand during DNA replication, which are later joined together by DNA ligase.

Front

Which enzyme unwinds the DNA double helix?

Back

DNA Helicase is the enzyme that unwinds the DNA double helix, separating the two strands to allow replication.

Front

What is the function of RNA Primase in DNA replication?

Back

RNA Primase synthesizes a short RNA primer that provides a starting point for DNA synthesis by DNA Polymerase.

Front

What is the lagging strand in DNA replication?

Back

The lagging strand is the DNA strand that is synthesized discontinuously in short segments (Okazaki fragments) away from the replication fork.

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 role of DNA Ligase?

Back

DNA Ligase is the enzyme that joins Okazaki fragments together on the lagging strand, sealing the gaps between them.

Front

What does it mean for DNA Polymerase to work in one direction?

Back

DNA Polymerase can only add nucleotides to the 3' end of a growing DNA strand, meaning it synthesizes DNA in the 5' to 3' direction.
