DNA Replication

Front

What is DNA Replication?

Back

A process in which DNA makes an exact copy of itself.

Front

What enzyme is responsible for adding nucleotides during DNA replication?

Back

DNA Polymerase.

Front

What is the role of Primase in DNA replication?

Back

Primase synthesizes short RNA primers that provide a starting point for DNA synthesis.

Front

What does Ligase do in DNA replication?

Back

Ligase joins Okazaki fragments on the lagging strand by forming phosphodiester bonds.

Front

What is the function of Helicase in DNA replication?

Back

Helicase unwinds the double helix and separates the two strands of DNA.

Front

What is the first step in the DNA replication process?

Back

The double helix straightens and unwinds.

Front

What follows the unwinding of the DNA double helix?

Back

Helicase breaks the hydrogen bonds between the base pairs.

Front

What is the sequence of events in DNA replication?

Back

1. Straightens the double helix 2. Breaks hydrogen bonds 3. Adds free nucleotides 4. Recoils the DNA.

Front

What is the difference between replication and transcription?

Back

Replication copies the entire DNA molecule, while transcription synthesizes RNA from a DNA template.

Front

What are Okazaki fragments?

Back

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