DNA, DNA Replication and the Cell Cycle (Mitosis)

Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA before cell division.

Front

Why is DNA replication important before cell division?

Back

It ensures that genetic information is accurately passed on to daughter cells.

Front

What are the components of a DNA nucleotide?

Back

A DNA nucleotide is made up of a sugar, a phosphate group, and a nitrogenous base.

Front

What forms the backbone of a DNA strand?

Back

The backbone of a DNA strand is made of sugar and phosphate molecules.

Front

What type of bond joins the nitrogenous bases in DNA?

Back

Hydrogen bonds.

Front

What is the role of the cell cycle?

Back

The cell cycle is the series of events that lead to cell division and replication.

Front

What are the main phases of the cell cycle?

Back

The main phases are Interphase (G1, S, G2) and Mitosis.

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication occurs during the S phase.

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 division of the cytoplasm to form two separate daughter cells after mitosis.
