Mitosis Flashcards
(31 cards)
What is the purpose of Cell Division
organisms to reproduce their own kind
What is cell division
reproduction at cellular level
What does cell division require to work
duplication of chromosomes
What are the uses of Cell Division
reproduction of single-cell organisms
growth of multicellular organisms
repair and replace cells
sperm and egg production
What are the two ways of cell division
Asexual reproduction
sexual reporduction
what does asexual reproduction produce
offspring that is identical to OG cell/organism
what does sexual reproduction produce
offspring that share similar to parents + show variation in traits
How to Prokaryotes reproduce
Binary fission
What are the three stages of binary fission
- duplication of chromosomes + separations of copies
- continued elongation of cell + movement of copies
- division into two daughter cells
Why are Eukaryotic cell division different than prokaryotic
more complex / larger
more genes
store most genes + chromosomes in nucleus
what is eukaryotic chromosomes composed of
chromatin
what is chromatin made of>
DNA + proteins
what are sister chromatids?
identical copies of chromosomes
what is a centromere
where sister chromatids are joined together before division
what are eukaryotes chromosomes look like
linear structure
what are prokaryotic chromosomes look like
circular structure
true or false: number of chromosomes is species specific
true
what are the two stages of the cell cycle
interphase
mitotic phase
what is mitotic phase
division
what is mitosis
division of the nucleus
what is cytokinesis
division of cytoplasm
what is interphase?
duplication of cell contents
what are the stages of mitotic division
- Prophase
- Prometaphase
- Metaphase
- Anaphase
- Telophase
- Cytophase
what happens during Interphase
(g1) growth, (S) DNA replication, (g2) growth
