Mitosis

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each having the same number of chromosomes as the original cell.

Front

How many chromosomes do fruit fly body cells have?

Back

Fruit fly body cells have 8 chromosomes.

Front

What is the result of mitosis in terms of chromosome number?

Back

After mitosis, the daughter cells have the same number of chromosomes as the original cell.

Front

What is the first phase of mitosis?

Back

The first phase of mitosis is prophase.

Front

What happens during prophase?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope begins to break down, and the mitotic spindle starts to form.

Front

What phase of mitosis is characterized by the separation of sister chromatids?

Back

Anaphase is characterized by the separation of sister chromatids.

Front

What occurs during telophase?

Back

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

Front

What do the cells look like at the end of mitosis?

Back

At the end of mitosis, the daughter cells are identical to the original cell.

Front

What is chromatin?

Back

Chromatin is the form of DNA that is loosely packed in the nucleus during interphase, allowing for gene expression and DNA replication.

Front

What is the role of the centromere?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together and where the spindle fibers attach during mitosis.
