DNA Structure and Replication

Front

What is the process in which DNA makes an exact copy of itself?

Back

Replication

Front

What does DNA replication result in?

Back

Two DNA molecules, each with one new strand and one original strand.

Front

What are the three components of a nucleotide?

Back

Deoxyribose sugar, phosphate, nitrogen base.

Front

What is a nucleotide?

Back

The basic building block of DNA, consisting of a deoxyribose sugar, a phosphate group, and a nitrogen base.

Front

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

Back

S phase.

Front

What is the structure of DNA?

Back

A double helix composed of two strands of nucleotides.

Front

What are the four nitrogen bases in DNA?

Back

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

Front

What base pairs with Adenine in DNA?

Back

Thymine (T).

Front

What base pairs with Cytosine in DNA?

Back

Guanine (G).

Front

What is the role of DNA polymerase in replication?

Back

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