CELL DIVISION Flashcards
0
Q
METAPHASE
A
- Microtubules produced by the centriole, attach to the centromere
- Chromosomes/ centromere aligns at the equator
1
Q
PROPHASE
A
- Nucleolus is disintegrated
- DNA is condensed/folded into chromosomes
- Chromosomes become visible under a light microscope
- Centrioles have begun to move to opposite poles
2
Q
ANAPHASE
A
- Microtubules contract with an equal but opposite force
- Centromere divides in 2
- Sister chromatids are pulled to opposite poles
3
Q
TELOPHASE
A
- Chromatids have arrived at poles
- Nuclear envelope reforms
- DNA decondenses and is now in form of chromatin
4
Q
CYTOKINESIS
A
• The equal division of the cells cytoplasm and organelles
5
Q
MITOSIS
A
- Diploid
* Genetically Identical
6
Q
MEIOSIS
A
- Haploid
* Not Genetically Identical
7
Q
Synthesis Phase
A
• DNA replicates
8
Q
Growth Phase 1
A
- Protein Synthesis takes place
* Organelles replicate
9
Q
Growth Phase 2
A
Cell increases in size
10
Q
Type of reproduction in yeast cells
A
Asexual
11
Q
Type of cell division in yeast cells
A
Mitosis
13
Q
Describe budding in yeast
A
- Nucleus divides by mitosis
- Cell swells on one side
- Nucleus, cytoplasm and organelles move into bud
- The bud pinches off and a new cell wall forms
- Bud becomes a separate cell
