A human cell cycle lasts approximately:
12 hours
06 hours
01 hours
24 hours
The cell cycle is the set of changes that take place in a newly created cell. It is the process by which a cell grows and divides to generate two daughter cells.
The cell cycle is divided into two stages: interphase and M phase.
The M Phase is the stage during which actual cell division or mitosis occurs. It is a brief dividing period.
The phase between two successive M phases is represented by interphase. It is a protracted period of non-dividing growth.
Interphase is separated into four stages: Gap 1 (G1), S (synthesis) phase, Gap 2 phase, and Gap 3 phase (G2).
G1 Phase - The G1 phase of the cell cycle lasts roughly 11-12 hours in a human cell.
The cell is metabolically active and expands continually during the G1 phase, but it does not duplicate its DNA.
S Phase - The S phase of the cell cycle lasts around 8 hours in a human cell.
The S or synthesis phase is the time when DNA synthesis or replication occurs.
G2 Phase - The G2 phase of the cell cycle lasts around 4 hours.
Proteins are generated in preparation for mitosis during the G2 phase, while cell development continues.
Phase M
In a human cell, the M phase of the cell cycle lasts roughly 1 hour.
Cell division occurs during this stage of the cell cycle.
A human cell's cell cycle, which consists of the Interphase and M phases, lasts 24 hours.
Hence, option 4 is the correct answer.
