Mitosis, Meiosis, Cell Cycle

Which process involves the division of a cell into two identical daughter cells?

• mitosis

• meiosis

• apoptosis

• cytokinesis

What is the purpose of mitosis?

• The purpose of mitosis is to ensure growth, repair, and replacement of cells in multicellular organisms.

• The purpose of mitosis is to eliminate damaged cells from the body.

• The purpose of mitosis is to generate energy for the cell.

• The purpose of mitosis is to produce gametes for sexual reproduction.

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

• G1 phase

• M phase

• S phase

• G2 phase

What is the purpose of DNA replication?

• The purpose of DNA replication is to create new genetic information.

• The purpose of DNA replication is to produce RNA molecules.

• The purpose of DNA replication is to ensure genetic continuity and the transmission of genetic information to the next generation.

• The purpose of DNA replication is to repair damaged DNA.

Which process involves the division of a diploid cell into four haploid cells?

• mitosis

• fertilization

• meiosis

• apoptosis

What is the purpose of meiosis?

• The purpose of meiosis is to produce somatic cells for asexual reproduction.

• The purpose of meiosis is to repair damaged cells in the body.

• The purpose of meiosis is to produce food for the organism.

• The purpose of meiosis is to produce gametes (sex cells) for sexual reproduction.

Which phase of meiosis involves the separation of homologous chromosomes?

• Telophase I

• Metaphase I

• Prophase I

• Anaphase I

What is the result of meiosis?

• Formation of gametes with double the number of chromosomes

• Formation of gametes with the same number of chromosomes

• Formation of somatic cells with half the number of chromosomes
