DNA and DNA Replication

Front

What is the structure of a DNA molecule?

Back

A DNA molecule is a double helix formed by two strands of nucleotides, consisting of a sugar-phosphate backbone and nitrogenous bases (adenine, thymine, cytosine, guanine) that pair specifically (A-T, C-G).

Front

What pairs with the DNA sequence ATG TGA CAG?

Back

The complementary DNA sequence is TAC ACT GTC.

Front

What determines the information in a DNA molecule?

Back

The order (sequence) of the nitrogen bases determines the code or information of a DNA molecule.

Front

Which nitrogen base does Guanine bond with?

Back

Guanine bonds with Cytosine.

Front

What is the order of DNA replication?

Back

The order of replication is 3, 4, 1, 2.

Front

What are the four nitrogen bases in DNA?

Back

The four nitrogen bases in DNA are Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

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

Back

The sugar-phosphate backbone provides structural support and stability to the DNA molecule.

Front

What is the significance of complementary base pairing in DNA?

Back

Complementary base pairing ensures accurate replication and transcription of genetic information.

Front

What is a mutation in DNA?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein structure and function.
