DNA Replication

Front

What is DNA replication?

Back

The process by which a cell makes an identical copy of its DNA, resulting in two DNA molecules, each containing one original strand and one newly synthesized strand.

Front

What is the role of DNA Polymerase in DNA replication?

Back

DNA Polymerase is the enzyme responsible for adding nucleotides to the growing DNA strand during replication.

Front

What is the leading strand in DNA replication?

Back

The leading strand is the DNA strand that is synthesized continuously in the 5' to 3' direction towards the replication fork.

Front

What are Okazaki fragments?

Back

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

Front

What is the function of helicase in DNA replication?

Back

Helicase unwinds the double-stranded DNA, separating the two strands to allow replication to occur.

Front

What is the lagging strand in DNA replication?

Back

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

Front

What is the significance of primase in DNA replication?

Back

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

Front

What is the role of ligase in DNA replication?

Back

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

Front

What is the difference between the leading and lagging strands?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short, discontinuous segments.

Front

What happens to the original DNA strands during replication?

Back

Each new DNA molecule consists of one original strand and one newly synthesized strand, preserving half of the original DNA.
