Multiple Choice
Which event occurs during meiosis but not during mitosis in typical animal cells?
A
DNA replication during S phase prior to nuclear division
B
Condensation of chromosomes and breakdown of the nuclear envelope
C
Separation of sister chromatids during anaphase
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 DNA replication during the S phase occurs before both mitosis and meiosis, so this event is common to both processes.
Recognize that condensation of chromosomes and breakdown of the nuclear envelope happen in both mitosis and meiosis, so this is not unique to meiosis.
Note that separation of sister chromatids during anaphase occurs in both mitosis and meiosis II, so this event is also not unique to meiosis as a whole.
Identify that synapsis of homologous chromosomes and crossing over during prophase I is a distinctive event of meiosis, where homologous chromosomes pair up and exchange genetic material, which does not occur in mitosis.
