Which event occurs during meiosis but not during mitosis in typical eukaryotic cells?
A
Separation of sister chromatids during anaphase
B
Alignment of individual duplicated chromosomes at the metaphase plate
C
DNA replication during S phase prior to cell division
D
Synapsis of homologous chromosomes and crossing over during prophase I
Verified step by step guidance1
Understand the key differences between mitosis and meiosis, focusing on the unique events that occur in meiosis but not in mitosis.
Recall that during mitosis, sister chromatids separate during anaphase, and duplicated chromosomes align individually at the metaphase plate, which also happens in meiosis but with differences.
Recognize that DNA replication during S phase occurs before both mitosis and meiosis, so it is not unique to meiosis.
Identify that synapsis of homologous chromosomes and crossing over occur specifically during prophase I of meiosis, where homologous chromosomes pair up and exchange genetic material, a process absent in mitosis.
Conclude that the event unique to meiosis is the pairing (synapsis) of homologous chromosomes and crossing over during prophase I, which increases genetic diversity.
