Biology Exam (Mitosis and Meiosis)

Front

What is the result of fertilization in humans?

Back

A zygote

Front

What is a chromatid?

Back

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

Front

Which phase of the cell cycle is responsible for DNA replication?

Back

S phase

Front

What structure ensures the equal distribution of chromosomes during cell division?

Back

Centrosome

Front

What is the primary function of meiosis in humans?

Back

Generating gametes

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What are gametes?

Back

Gametes are reproductive cells (sperm and eggs) that unite during fertilization to form a zygote.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical cells, while meiosis results in four genetically diverse gametes.

Front

What is a zygote?

Back

A zygote is the fertilized egg formed by the union of a sperm and an egg.

Front

What is the role of the centrosome during cell division?

Back

The centrosome organizes the microtubules that separate chromosomes during cell division.
