Front

What are the phases of the cell cycle that include G1, S, and G2?

Back

Interphase

Front

What is the significance of crossing-over in meiosis?

Back

It allows for genetic recombination within gametes, contributing to genetic diversity.

Front

How many times does interphase occur in meiosis?

Back

Once

Front

What percentage of the cell is typically in mitosis?

Back

15 Percent

Front

What is mitosis?

Back

A process of cell division that results in two identical daughter cells.

Front

What is meiosis?

Back

A type of cell division that reduces the chromosome number by half, producing four gametes.

Front

What is the main purpose of meiosis?

Back

To produce gametes for sexual reproduction.

Front

What happens during the S phase of interphase?

Back

DNA replication occurs, resulting in two copies of each chromosome.

Front

What is the difference between somatic cells and gametes?

Back

Somatic cells are body cells with a full set of chromosomes, while gametes are reproductive cells with half the number.
