Cell Cycle and Cancer Review

Front

Explain how the structure of DNA allows for it to be easily copied

Back

The structure of DNA, with its double helix formation and complementary base pairing, allows for easy replication as each strand serves as a template for the new strand.

Front

What is the rule that explains how nucleotides are added to during replication?

Back

A + T

C + G

Front

The deoxyribose sugar and phosphate make up what structure of the DNA?

Back

The backbone of the DNA.

Front

What is meant by ‘semi-conservative’ when referring to DNA replication?

Back

It means that each new DNA molecule consists of one old strand and one new strand.

Front

Explain why the structure of DNA is called a double helix.

Back

Because it consists of two strands that twist around each other.

Front

Cells divide during what phase of the cell cycle?

Back

Mitosis.

Front

How does mitosis look different in cancerous cells compared to healthy cells?

Back

Cancerous cells divide uncontrollably and show abnormal rates of mitosis

Front

Explain how tumor suppressor genes function in regards to cancer in the body.

Back

They normally help regulate cell division and prevent tumor formation.

Front

How a mutation to tumor suppressor genes will affect the cells?

Back

It can lead to uncontrolled cell growth.

Front

How this will lead to cancer?

Back

Uncontrolled cell growth can result in tumor formation.
