CP bio DNA and Cell Cycle

Front

What is DNA replication?

Back

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

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What does semi-conservative replication mean?

Back

It refers to the method of DNA replication where each new DNA molecule consists of one original strand and one newly synthesized strand.

Front

What is the function of helicase in DNA replication?

Back

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

Front

What occurs during the G1 phase of the cell cycle?

Back

The cell grows, performs its normal functions, and prepares for DNA replication.

Front

What is the significance of the S phase in the cell cycle?

Back

The S phase is when DNA replication occurs, resulting in the duplication of the genetic material.

Front

What is the M phase in the cell cycle?

Back

The M phase is the mitotic phase where the cell divides its copied DNA and cytoplasm to form two new cells.

Front

What is the role of ligase in DNA replication?

Back

Ligase joins Okazaki fragments on the lagging strand, sealing nicks in the sugar-phosphate backbone.

Front

What are Okazaki fragments?

Back

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

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.
