PRACTICE QUIZ—3/24
1. In what phase of meiosis are homologous chromosomes separated? Anaphase I
Mitosis? Doesn’t occur!
2. In what phase of meiosis are sister chromatids separated? Anaphase II
Mitosis? Anaphase
3. Other DNA-containing organelles besides the nucleus (such as mitochondria) replicate
their DNA through what process? Binary fission
4. What is metastasis? When cells detach from neighboring cells and spread in the
body. How are cancer cells different from non-cancer cells? They’re not inhibited by
density, they tend to grow more quickly and they do not obey cell cycle checkpoints.
5. When does synapsis occur during meiosis? Prophase I
Crossing over? Prophase I Crossing over produces recombinant chromosomes and
increases genetic variation (as does independent assortment!).
6. The end result of mitosis is 2 genetically identical daughter cells.
The end result of meiosis is 4 genetically different, haploid daughter cells.
