DNA Replication

Front

What is the role of helicase in DNA replication?

Back

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

Front

True or False: The new DNA strand formed after DNA replication is an exact copy of its parent strand.

Back

True

Front

List the steps of DNA replication in order: 1. Recoil 2. Straightens the double helix 3. Breaks Hydrogen bonds 4. Adds Free nucleotides.

Back

2, 3, 4, 1

Front

What enzyme is responsible for adding nucleotides during DNA replication?

Back

Polymerase is the enzyme that adds free nucleotides to the growing DNA strand.

Front

What is DNA replication?

Back

DNA replication is the process by which DNA makes an exact copy of itself.

Front

What is the function of primase in DNA replication?

Back

Primase synthesizes a short RNA primer that provides a starting point for DNA polymerase to begin replication.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

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 is the role of ligase in DNA replication?

Back

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

Front

What are Okazaki fragments?

Back

Okazaki fragments are short sequences of DNA nucleotides synthesized on the lagging strand during DNA replication.
