Exam 3 Test Review
True/False
1. ____Binary fission is a type sexual reproduction that prokaryotes undergo.
2. ____ Adult stem cells found in the hippocampus are able to differentiate into
many other types of cells therefore they are totipotent.
3. ____ You will see tetrads (homologous pairs) line up at the metaphase plate
during metaphase II of mitosis.
4. ____ There are three stages of embryonic cell development, they are:
fertilization, cleavage (blastula formation) and gastrulation.
5. ____ Sister chromatids will separate during metaphase II of meiosis.
6. ____ The kinetichore will break during anaphase, which requires ATP energy.
7. ____ Mitosis produces genetically identical daughter cells and meiosis
produces genetically unique gametes.
8. ____ The kinetochore is a specialized protein that lies on top of the centriole
region of chromosomes.
9. ____ The purpose of mitosis is the repair of damaged tissue and growth.
10. ____ Mitosis produces four cells whereas meiosis produces two cells.
