chapter 11 Flashcards
cell division
1
Q
cell theory
A
all cells come from pre existing cells
2
Q
cell division
A
the process in which cells make more cells.
- continuous
- 1 cell = 2 daughter cells
- m phase + interphase
3
Q
DNA replication
A
a single parent molecule of DNA produces two daughter cells
4
Q
cancer
A
results from a loss of control of cell division
5
Q
cell cycle
A
DNA replication followed by cell division
- the life cycle begins and ends with cell division
= M phase + interphase
6
Q
binary fission
A
process by which prokaryote cells produce daughter cells.
- form of cell division
7
Q
m phase
A
consists of 2 different events.
1.mitosis- the separation of the chromosomes into two nuclei
2.cytokinesis - the division of the cell itself into two separate cells
8
Q
interphase
A
- time between two successive M phases
- divided into 3 phases
-prepares for cell division by DNA replication and cell growth
9
Q
phases of interphase
A
- s phase - DNA replication. synthesis .
- G1phase -
- G2 phase -
10
Q
G0 phase
A
gap phase between
