DNA Replication

Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA before cell division.

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

How do nitrogenous bases pair in DNA?

Back

Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-G).

Front

What is the role of the sugar-phosphate backbone in DNA?

Back

It provides structural support and stability to the DNA molecule.

Front

Where is DNA located in eukaryotic cells?

Back

In the nucleus.

Front

What is the function of DNA?

Back

To store and transmit genetic information that determines an organism's traits.

Front

What phase of the cell cycle does DNA replication occur?

Back

During the S phase (Synthesis phase).

Front

What enzyme is responsible for unwinding the DNA double helix during replication?

Back

Helicase.

Front

What is the role of DNA polymerase?

Back

To synthesize new DNA strands by adding nucleotides complementary to the template strand.
