Front

What phase of the cell cycle does DNA replication occur?

Back

S phase

Front

What are the three components of a nucleotide?

Back

Sugar, phosphate, nitrogen base

Front

How would you describe the structure of a DNA molecule?

Back

Double helix

Front

In double-stranded DNA, which base pairs with Adenine?

Back

Thymine

Front

What is the result of DNA replication?

Back

Each DNA molecule has one new strand and one original strand.

Front

What is the role of DNA in cells?

Back

DNA stores genetic information and instructions for protein synthesis.

Front

What is the function of helicase in DNA replication?

Back

Helicase unwinds the double helix structure of DNA.

Front

What is the significance of complementary base pairing in DNA?

Back

It ensures accurate replication and transcription of genetic information.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose; RNA is single-stranded and contains ribose.

Front

What is a mutation?

Back

A change in the DNA sequence that can lead to changes in protein function.
