Prokaryotic cells Flashcards
1
Q
Structure of prokaryotic cells
A
- single celled
- lack of membrane bound organelles
- single circular chromosome of DNA
- Have plasmids
- Ribosome for protein synthesis
2
Q
Prokaryotic reproduction
A
asexual by binary fission
3
Q
example of prokaryotic cell
A
bacteria
4
Q
Interphase
A
G1 phase - cell growth & protein synthesis
S phase - DNA replication
G2 phase - Cell growth & prep for mitosis
5
Q
Prophase
A
Plump chromosones
Chromosomes condense, nuclear envelope breaks down, spindle fibres form
6
Q
Metaphase
A
Middle lining up
Chromosomes line up at the equator of the cell
7
Q
Anaphase
A
(pulled) appart
sister chromatids seperate and move to opposite poles of the cell
8
Q
Telaphase
A
two nuclei are forming
Nuclear envelopes form around the chromosomes, chromosomes unravel.
9
Q
Cytokinesis
A
cells split
Cytoplasm divides, forming 2 genetically identical daughter cells
10
Q
the cell cycle
A
