Mitosis and DNA

Front

What is Mitosis?

Back

Mitosis is the process by which a single cell divides to produce two identical daughter cells, ensuring that each new cell has the same number of chromosomes as the original cell.

Front

What are the main phases of Mitosis?

Back

The main phases of Mitosis are Prophase, Metaphase, Anaphase, and Telophase.

Front

What happens during Prophase?

Back

During Prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle apparatus begins to form.

Front

What occurs during Metaphase?

Back

During Metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is Anaphase?

Back

Anaphase is the stage of Mitosis where sister chromatids are pulled apart to opposite poles of the cell.

Front

What happens during Telophase?

Back

During Telophase, the chromosomes reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense.

Front

What is Cytokinesis?

Back

Cytokinesis is the process that follows Mitosis, where the cytoplasm divides, resulting in two separate daughter cells.

Front

What are Chromosomes?

Back

Chromosomes are structures within the nucleus made of DNA and proteins that carry genetic information.

Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for life, composed of two strands forming a double helix.

Front

What must be copied before a cell can divide?

Back

Before a cell can divide, its DNA must be copied to ensure that each daughter cell receives an identical set of genetic information.
