Unit 6 Cell Cycle

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase and mitotic phase.

Front

What happens during DNA replication?

Back

During DNA replication, the double helix unwinds and the base pairs separate, allowing new complementary strands to form.

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are interphase (G1, S, G2) and mitotic phase (M).

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell grows, duplicates its DNA, and prepares for mitosis.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells.

Front

What are checkpoints in the cell cycle?

Back

Checkpoints are regulatory points in the cell cycle that ensure the cell is ready to proceed to the next phase.

Front

What is the role of cyclins in the cell cycle?

Back

Cyclins are proteins that regulate the timing of the cell cycle in eukaryotic cells.

Front

What is cancer in relation to the cell cycle?

Back

Cancer is a disease characterized by uncontrolled cell division, often due to mutations that affect cell cycle regulation.

Front

What is the significance of hydrogen bonds in DNA?

Back

Hydrogen bonds between nitrogenous bases hold the two strands of DNA together, allowing for the double helix structure.

Front

What are nitrogenous bases?

Back

Nitrogenous bases are the building blocks of DNA and RNA, consisting of adenine, thymine, cytosine, guanine, and uracil.
