10-2 cell division
Telophase
A nuclear envelope reforms around each cluster of chromosomes. The nucleus becomes visible in each daughter nucleus
G1 phase
Cells do most of their growing increasing in size and synthesizing new proteins and organelles
S
Chromosomes are replicated and the synthesis of DNA molecules take place. also, keep proteins associated with the chromosomes are synthesized
When chromosomes become visible at the beginning of cell division, what does each chromosome consist of?
Each chromosome consists of two identical sister chromatids
Centromere
Each pair of chromatids is attached to an area called
Cell plate
It forms midway between the divided nucleus during cytokinesis in plant cells
G2
Many of the organelles and molecules required for cell division are produced
How does cytokinesis occur in most animal cells?
The cell membrane is drawn in word until the cytoplasm is pinched into two nearly equal parts
Prophase
The chromosomes become visible. The centrioles take up positions on opposite sides of the nucleus.
Metaphase
The chromosomes line up across the center of the cell
Anaphase
The chromosomes move until they form two groups near the poles of the spindle
Cytokinesis
The division of the cytoplasm itself
Prophase, metaphase, anaphase phase, telophase
The four phases of mitosis
Interphase
The period of growth in between cell divisions
Cell cycle
The series of events that cells go through as they grow and divide
Spindle
The spindle is a fanlike microtuble structure that help separate the chromosomes
G1, S, G2
The three phases interface is divided into
Centrioles
To Teenies structure is located in the cytoplasm near the nuclear envelope at the beginning of prophase
Mitosis and cytokinesis
Two main stages of cell division
