Mitosis and Meiosis Flashcard

Front

What is the end result of meiosis?

Back

4 genetically different cells.

Front

What is the centromere?

Back

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

Front

How many chromosomes do daughter cells have after meiosis?

Back

23 chromosomes.

Front

What is the end result of mitosis?

Back

2 identical cells are produced.

Front

During which phase does crossing over occur?

Back

Crossing over occurs during Prophase I of meiosis.

Front

Define mitosis.

Back

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

Front

Define meiosis.

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically different gametes.

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 the centromere.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including DNA replication.
