DNA Replication BellRinger

Front

What is the structure of a DNA molecule?

Back

A DNA molecule is structured as a double helix, consisting of two strands that wind around each other.

Front

What base pairs with Adenine (A) in DNA?

Back

Thymine (T) pairs with Adenine (A) in DNA.

Front

What is the role of nucleotides in DNA replication?

Back

Nucleotides are the building blocks of DNA; they pair with complementary bases to form new strands during replication.

Front

What direction does DNA replication occur?

Back

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

Front

What does 'antiparallel' mean in the context of DNA strands?

Back

Antiparallel refers to the orientation of the two strands of DNA, where one strand runs 5' to 3' and the other runs 3' to 5'.

Front

In 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 result of DNA replication?

Back

DNA replication results in two DNA molecules, each containing one original strand and one newly synthesized strand.

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

What is the function of DNA helicase during replication?

Back

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

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.
