Mitosis and Meiosis Review

Front

What is mitosis?

Back

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

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse daughter cells, each with half the number of chromosomes of the parent cell.

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 resulting daughter cells have the same number of chromosomes as the parent cell.

Front

What is the significance of DNA replication before cell division?

Back

DNA replication is crucial before cell division to ensure that each daughter cell receives an exact copy of the genetic information.

Front

What are chromosomes?

Back

Chromosomes are structures made of condensed DNA that carry genetic information.

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 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 de-condense back into chromatin, the nuclear envelope re-forms, and the cell prepares to divide.
