Cell Cycle Flashcards
1
Q
What is the “central dogma” of molecular biology?
A
- Information in DNA transferred to mRNA via transcription
- Protein created by a ribosome and tRNA using information contained in mRNA
2
Q
What is the cell cycle?
A
Series of events that takes place in a cell leading to its division and duplication
3
Q
Why do cells divide?
A
Reproduction, growth, and repair
4
Q
What phases make up interphase?
A
G1, G0, S, G2
5
Q
What are the characteristics of G0?
A
The cell is quiescent; occurs in senescent cells
6
Q
What are the characteristics of G1?
A
Growth phase; biochemical fxn occurs (e.g. protein synthesis)
7
Q
What are the characteristics of S?
A
Synthesis - DNA replication
8
Q
What are the characteristics of G2?
A
Microtubules
9
Q
What is a pluripotent cell?
A
A cell that is able to differentiate into all cell types, AKA a stem cell
