DNA Structure and Replication

Front

What is the first step in the process of DNA replication?

Back

An enzyme called helicase 'unzips' the DNA molecule by breaking the hydrogen bonds.

Front

What must be done with the DNA before a cell can go through division (mitosis)?

Back

DNA replication.

Front

What makes up the rungs (center) of a DNA ladder?

Back

Nitrogen bases.

Front

Which sequence of DNA bases would pair with this partial strand: ATG TGA CAG?

Back

TAC ACT GTC.

Front

What does DNA stand for?

Back

Deoxyribonucleic acid.

Front

What are the four nitrogen bases found in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and 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 structure of DNA commonly described as?

Back

A double helix.

Front

What is the function of the enzyme ligase during DNA replication?

Back

Ligase joins Okazaki fragments on the lagging strand.

Front

What is the significance of complementary base pairing in DNA?

Back

It ensures accurate replication and transcription of genetic information.
