GENERAL Flashcards
What is cell division ?
it is a biochemical process during which a parent cell give rise to daughter cell.
What is cell cycle ?
It is a sequence of events during which a cell duplicates its own genome , synthesis other biomolecules of cells undergo growth and eventually divides into two daughter cell .
All the events are under genetic control and occur in coordinated manner .
Who first studied cell cycle ?
Howard and Pelc in 1953
What are the two phases of cell cycle ?
- Interphase \ I-phase
2. M-Phase \ mitotic \ meiotic \ multiplicative phase
LEARN THE DIAGRAM OF TEH CELL CYCLE
DONE :D
What are the part of M-phase ?
- Karyokinesis
- Prophase
- Metaphase
- Anaphase
- Telophase
- Cytokinesis
What is the duration of the cell cycle in various organism ?
The duration if the cell cycle may vary from the organism to organism and from cell to cell .
What time does the yeast cell takes to divide ?
It takes 90 mins
What time does the human cell takes to divide ?
It takes 24hrs - 23hrs = Interphase , 1hrs = M phase
What happens to the cells of the stomach and small intestine ?
The cells here are replaced after every 3days due to the high acidic environment.
