Definition

Highly regulated sequence of growth, DNA replication, and division in eukaryotic cells.

1 / 13
Cell Cycle
Not Started

Highly regulated sequence of growth, DNA replication, and division in eukaryotic cells.

4.5.A4.5.A.1
G0 Phase
Not Started

Nondividing state where cells exit the cycle or pause until receiving appropriate signals.

4.5.A4.5.A.1
Sister Chromatids and Centromere
Not Started

Identical DNA copies joined at a centromere after replication during S phase.

4.5.A4.5.A.1
Mitosis
Not Started

Nuclear division that produces two genetically identical daughter cells with complete genomes.

4.5.B4.5.B.1
Functions of Mitosis
Not Started

Enables growth, tissue repair, and asexual reproduction in eukaryotic organisms.

4.5.B4.5.B.1
Mitotic Spindle
Not Started

Microtubule structure that attaches to chromosomes and moves them during mitosis.

4.5.B4.5.B.1
Kinetochores
Not Started

Protein structures on centromeres where spindle fibers attach to move chromatids.

4.5.B
Cytokinesis
Not Started

Division of the cytoplasm that produces two separate daughter cells after mitosis.

4.5.B4.5.B.1
Centrosomes
Not Started

Microtubule-organizing structures that replicate before mitosis and move to opposite poles.

4.5.A4.5.A.1
Chromatin
Not Started

Uncondensed DNA-protein complex present during interphase and replicated in S phase.

4.5.A4.5.A.1
Interphase
Not Started

G1, S, and G2 make up the stage when cells grow, replicate DNA, and prepare for division.

4.5.A4.5.A.1
Stages of Mitosis
Not Started

Prophase condenses chromosomes, metaphase aligns them, anaphase separates chromatids, and telophase reforms nuclei.

4.5.B4.5.B.1
Cytokinesis in Animal and Plant Cells
Not Started

Animal cells form a cleavage furrow, while plant cells build a cell plate.
