Cancer and Cell Cycle Flashcard Review S131

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides.

Front

What are the three main phases of Interphase?

Back

The three main phases of Interphase are G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

Front

What occurs during the S phase of Interphase?

Back

During the S phase, DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is the significance of the G1 phase in the cell cycle?

Back

The G1 phase is crucial for cell growth and preparation for DNA synthesis.

Front

What is the role of the G2 phase in the cell cycle?

Back

The G2 phase involves further growth and preparation for mitosis, including the synthesis of proteins necessary for cell division.

Front

What happens during Metaphase of mitosis?

Back

During Metaphase, chromosomes align at the cell's equatorial plane, preparing for separation.

Front

What is cancer in terms of cell growth?

Back

Cancer is characterized by uncontrolled cell growth and division, leading to the formation of tumors.

Front

What is the purpose of checkpoints in the cell cycle?

Back

Checkpoints in the cell cycle ensure that the cell is ready to proceed to the next phase, preventing errors in cell division.

Front

What is apoptosis and its role in cancer prevention?

Back

Apoptosis is programmed cell death that helps eliminate damaged or unnecessary cells, playing a role in preventing cancer.
