Term
Interphase
Definition
The cell grows and replicates its DNA and centrioles.contains G1, G2, and S phases.
Term
Prophase
Definition
Chromatin turns into chromosomes, the centrioles separate, and a spindel begins to form. The nuclear envelope breaks down.
Term
Metaphase
Definition
The chromosomes line up across the center of the cell. Each chromosome is connected to a spindle fiber at its centromere.
Term
Anaphase
Definition
The sister chromatids separate into individual chromosomes and are moved apart.
Term
Telophase
Definition
The chromosomes gather at opposite ends of the cell and lose their distinct shapes. Two new nuclear envelopes will form.
Term
Cytokinesis
Definition
The cytoplasm pinches in half. Each daughter cell has an identical set of duplicate chromosomes.
Term
Mitosis
Definition
The first phase of M phase. contains prophase,metahase, anaphase, and telophase.
Term
G1 phase
Definition
happens first in interphase, where cell do most of the growing
Term
Spindle
Definition
separates chromosomes.
Term
M phase
Definition
contains mitosis and cytokinesis
Term
S phase
Definition
happens second in interphase, where chromosomes replicate
Term
G2 phase
Definition
happens third in the interphase, many of the organelles and molecules required for cell division are produced
