DNA Structure and Replication

Front

What is the goal of DNA replication?

Back

To make an identical copy of DNA.

Front

What must occur with DNA before a cell can undergo division (mitosis)?

Back

DNA replication.

Front

Describe the two DNA molecules produced during DNA replication.

Back

Each molecule has an original side and a new side.

Front

What are nucleotides composed of?

Back

Sugar, Phosphate, Nitrogen Base.

Front

What is the correct complementary nitrogen base pairing for DNA?

Back

T-A, G-C.

Front

What is the structure of DNA?

Back

DNA is 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 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 is the significance of the semi-conservative model of DNA replication?

Back

In the semi-conservative model, each new DNA molecule consists of one old strand and one new strand.

Front

What is the function of helicase in DNA replication?

Back

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