The centromere is the region where spindle fibers attach during cell division to facilitate chromosome movement.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Cell Cycle - Phases G1 S G2 M and Regulation
G2 phase follows the S phase and involves the synthesis of proteins required for mitosis.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Cell Cycle - Phases G1 S G2 M and Regulation
The S phase (synthesis phase) is when DNA replication occurs, doubling the genetic material in preparation for cell division.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Cell Cycle - Phases G1 S G2 M and Regulation
During G2 phase, the cell prepares for mitosis by growing and synthesizing proteins required for division.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Cell Cycle - Phases G1 S G2 M and Regulation
Chromosome segregation occurs during mitosis, whereas interphase is mainly for growth, DNA replication, and preparation for division.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Cell Cycle - Phases G1 S G2 M and Regulation
DNA replication occurs in the S phase, ensuring each daughter cell receives an identical set of genetic material.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Cell Cycle - Phases G1 S G2 M and Regulation
Some cells in G0 can re-enter the cell cycle under specific conditions.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Cell Cycle - Phases G1 S G2 M and Regulation
DNA replication occurs in the S phase, not in G2.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Cell Cycle - Phases G1 S G2 M and Regulation
The G2 phase is a checkpoint where the cell ensures that DNA replication was completed correctly before mitosis begins.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Cell Cycle - Phases G1 S G2 M and Regulation
Kinetochores are protein structures at the centromere that facilitate chromosome movement by attaching to spindle fibers.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Cell Cycle - Phases G1 S G2 M and Regulation
G1 phase comes before the S phase, not after it.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Cell Cycle - Phases G1 S G2 M and Regulation
Nerve and heart cells remain in G0 permanently, while some other cells may re-enter the cycle under specific conditions.
