Cell Cycle and DNA Review

Front

What is the structure of DNA?

Back

DNA is a double helix made up of nucleotides, which consist of a sugar, a phosphate group, and a nitrogen base.

Front

What are the four nitrogen bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the base pairing rule in DNA?

Back

A pairs with T, and C pairs with G.

Front

What is the function of DNA?

Back

DNA stores genetic information and provides instructions for the development and functioning of living organisms.

Front

What happens during DNA replication?

Back

The DNA molecule unwinds and separates into two strands, each serving as a template for the formation of a new complementary strand.

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 are the phases of the cell cycle?

Back

The cell cycle consists of Interphase (G1, S, G2) and the Mitotic phase (M).

Front

What occurs during interphase?

Back

During interphase, 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 identical daughter cells.

Front

What is cytokinesis?

Back

Cytokinesis is the final step of cell division where the cytoplasm divides, resulting in two separate cells.
