Cell Cycle Flashcards
1
Q
A rare genetic syndrome in which some signs of aging are greatly accelerated.
A
PROGERIA
2
Q
It has 23 chromosomes haploid cells.
A
GAMETES
3
Q
It has 46 chromosomes Diploid cells.
A
SOMATIC CELLS
4
Q
One copy of each chromosome.
A
HAPLOID (n)
5
Q
Two copies of each chromosome.
A
Diploid (2n)
6
Q
A series of events that takes place in a cell as it grows and divides.
A
CELL CYCLE
7
Q
Divided into 2 gap phases and 1
synthesis phase.
A
INTERPHASE
8
Q
Is divided into four stages plus
A
MITOSIS
9
Q
When the cells separate.
A
CYTOKENESIS
10
Q
Is a “time-out” when a cell “decides” which
course of action to follow
A
G0
11
Q
- follows mitosis, when the cell resumes synthesis of proteins, lipids, and carbohydrates essential for early growth
- varies in different cell types
A
G1 Phase
12
Q
- the cell replicates its entire genome
- takes 8 to 10 hours
- proteins involved in formation of mitotic spindle are synthesized
- microtubules form centrioles
A
S Phase
13
Q
- occurs after DNA replication and before mitosis
- more proteins are synthesized
- prepares for cell division by assembling necessary structures
A
G2 Phase
14
Q
- produces two daughter cells of the same quality and quantity of chromosomes as the parent cell
- “duplication division”
- karyokinesis + cytokinesis
- has 4 distinct stages: prophase, methaphase, anaphase, and telophase
A
MITOSIS
15
Q
- DNA coils tightly, shortening and thickening the chromosomes.
- microtubules assemble from tubulin building blocks in the cytoplasm, forming the spindles.
- nuclear membrane breaks down.
- nucleolus is no longer visible.
A
Prophase
