Mitosis

Front

What is Mitosis?

Back

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

Front

What stage of the cell cycle do cells spend 90% of their time?

Back

Interphase.

Front

In which phase of Mitosis do the chromosomes pull apart?

Back

Anaphase.

Front

What is a Chromosome?

Back

A chromosome is a long, thread-like structure made of DNA and proteins that contains genetic information.

Front

What is a Chromatid?

Back

A chromatid is one half of a duplicated chromosome, which is joined to the other half by a centromere.

Front

What is a Centromere?

Back

A centromere is the region of a chromosome where the two sister chromatids are joined together.

Front

Why is it important to replicate DNA before cell division?

Back

It is important to replicate DNA before cell division to ensure that genetic information is accurately transferred to daughter cells.

Front

What happens during Prophase?

Back

During Prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and spindle fibers begin 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.

Front

What is Telophase?

Back

Telophase is the final stage of mitosis where the chromosomes de-condense, the nuclear envelope re-forms, and the cell prepares to divide.
