C’s Of The Cell Cycle Flashcards
1
Q
DNA
A
- Blueprints/instructions that make you unique
- Not supercoiled when in it’s simplest form
- Codes for protein
2
Q
DNA Replication
A
- 1n to 2n and 2n to 4n
- DNA turned into two exact copies of DNA
- Occurs during the S phase of interphase
3
Q
Nuclear Division
A
- Mitosis
4
Q
Cellular Division
A
- Cytokinesis
5
Q
Centromere
A
- Where spindle fibers attach
- Where sister chromatids are attached
6
Q
Chromatid
A
- Super coiled/condensed DNA
- Either attached to a sister or found alone (can be both considered this)
7
Q
Chromosome
A
- Supercoiled DNA
- Not necessarily attached to it’s replica
8
Q
Chromatin
A
- DNA that has coiled twice but not yet supercoiled
- Is the thread that makes up supercoiled chromosomes
9
Q
Sister Chromatids
A
- Makes up a chromosome that has replicated
- Are attached to the centromere
10
Q
Centriole
A
- Source of spindle fibers
- Anchor at the opposite sides (poles) of a cell
- Involved in organizing chromosomes during mitosis
11
Q
Spindle Fibre
A
- Attach to centromere
- Used to control movement of chromosomes during mitosis
12
Q
Diploid
A
- 2 sets of chromosomes
- In human cells is 2(23) = 46
13
Q
Haploid
A
- 1set of chromosomes (n)
- In human cells is 1(23) = 23
14
Q
Tetraploid
A
- 4 sets of chromosomes
- 4n or 2(2n)
- In human cells is 4(23) = 92 or 2(23) + 2(23) = 92
