AND ANSWERS



Phases of Mitosis - Correct Answers -Prophase, Metaphase, Anaphase, Telophase,

- DNA replicates

Prophase - Correct Answers -- Nuclear membrane disintegrates
- Nucleolus disappears
- Chromosomes condense
- Spindle apparatus begins to form between the poles

Meiosis - Correct Answers -Process which animal cells go through

Crossing Over - Correct Answers -- Exchange of chromosomal segments between a
pair of homologous chromosomes during Prophase 1 of meiosis
- Occurs during Interphase
- Helps with genetic variety

Apoptosis - Correct Answers -Programmed cell death

Stem Cell - Correct Answers -- Unspecialized cell that can develop into a specialized
cell under the right conditions
- Scientists using cell to create new treatments for many diseases and conditions

Metaphase - Correct Answers -Chromosomes attach to spindle apparatus and align
along equator of the cell

Anaphase - Correct Answers -Microtubules shorten, moving chromosomes to opposite
poles

Telophase - Correct Answers -- Chromosomes reach poles of cell
- Nuclear envelope re-forms
