Cellular Reproduction Practice

What is the process by which a cell divides into two identical daughter cells called?

• cytokinesis

• mitosis

• meiosis

• apoptosis

Which type of cell division is responsible for the growth and repair of body cells?

• budding

• mitosis

• binary fission

• meiosis

During which phase of the cell cycle does DNA replication occur?

• G2 phase

• S phase

• G1 phase

• M phase

What is the purpose of DNA replication?

• To ensure each new cell receives an identical copy of genetic information.

• To produce RNA molecules.

• To repair damaged DNA.

• To create genetic diversity in offspring.

What are the two main stages of cell division in eukaryotic cells?

• meiosis and apoptosis

• interphase and anaphase

• prophase and telophase

• mitosis and cytokinesis

What is the purpose of mitosis?

• To repair damaged cells in the body.

• To ensure each new cell receives an identical copy of the genetic material (DNA) from the parent cell.

• To produce haploid cells for sexual reproduction.

• To create genetic diversity in offspring.

How many chromosomes are present in a human body cell?

• 46

• 50

• 32

• 23

What is the purpose of meiosis?

• To produce gametes with half the number of chromosomes.

• To produce gametes with double the number of chromosomes.

• To produce somatic cells with half the number of chromosomes.

• To produce gametes with the same number of chromosomes as the parent cells.

During which phase of meiosis does crossing over occur?

• metaphase I

• anaphase I

• telophase I

• prophase I

What is the difference between mitosis and meiosis?

• The main difference between mitosis and meiosis is the number of daughter cells produced and the genetic variation in the daughter cells.

• Mitosis and meiosis occur in the same phase of the cell cycle.

• Mitosis and meiosis produce daughter cells with identical genetic information.

• Mitosis and meiosis produce the same number of daughter cells.
