Crossing over during mitosis
Independent assortment of chromosomes
Random mutations during DNA replication
Conjugation with another individual
Which statement about the comparison of mitosis and meiosis is FALSE?
Mitosis results in two diploid cells, while meiosis results in four haploid cells.
Mitosis involves one cell division, while meiosis involves two.
Mitosis produces genetically identical cells, while meiosis produces genetically diverse cells.
Homologous chromosomes behave similarly in mitosis and meiosis.
Which process is NOT directly involved in the growth and repair of damaged tissues in multicellular organisms?
Mitosis
Meiosis
DNA Replication
Protein Synthesis
Which of the following statements accurately describes the process of DNA replication?
