DNA structure and Replication

Front

What is the shape of DNA?

Back

Double helix (twisted ladder)

Front

What do nucleotides consist of?

Back

Nucleotides consist of a phosphate, a sugar, and a base, but NOT a nucleic acid.

Front

What determines the code within a DNA molecule?

Back

The order (sequence) of the nitrogen bases.

Front

What does DNA stand for?

Back

Deoxyribo-Nucleic Acid.

Front

What makes up the sides of a DNA ladder (the backbone of DNA)?

Back

Deoxyribose sugars & phosphates.

Front

What are the building blocks of DNA?

Back

Nucleotides.

Front

What are the four nitrogen bases in DNA?

Back

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

Front

How do nitrogen bases pair in DNA?

Back

Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-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 process of DNA replication?

Back

DNA replication is the process by which a DNA molecule makes a copy of itself before cell division.
