DNA Replication BellRinger

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 are the two strands of DNA molecules produced during replication?

Back

Each DNA molecule consists of one new strand and one original strand.

Front

In which direction does DNA replication occur?

Back

DNA replication occurs from the 5' to 3' direction.

Front

What does it mean for DNA strands to be antiparallel?

Back

Antiparallel means that the two strands of DNA run in opposite directions.

Front

What is the function of helicase in DNA replication?

Back

Helicase is the enzyme that unzips the DNA double helix to prepare for replication.

Front

During which phase of the cell cycle does DNA replication occur?

Back

DNA replication occurs during the S phase of the cell cycle.

Front

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

Back

The S phase is crucial for DNA replication, ensuring that each daughter cell receives an identical set of chromosomes.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

How do adenine and thymine pair in DNA?

Back

Adenine pairs with thymine through two hydrogen bonds.
