Cell Cycle and Mitosis Vocab CP
includes G1, S and G2 phases. It is the stage a cell spends most of its time. It is carrying out its role, taking in energy, making proteins, getting rid of waste, etc.
first stage of Interphase
When most cell work is done
Time during interphase when DNA replication takes place
second growth phase during interphase when organelles are copied and any other materials for cell division are prepared
the division of the nucleus
includes: Prophase, metaphase, anaphase, and telophase
The nucleus begins to break down
Chromatin condenses to form chromosomes which pair with their identical copies.
Centrioles begin to move to opposite ends of cell
Sister chromatids move towards the equator of the cell. Spindle fibers attach to the centromeres.
Spindle fibers pull sister chromatids apart and then individual chromosomes begin to move to opposite ends of cell
Chromosomes have reached the poles, a new nucleus begins to reform around them and then the chromosomes begin to uncoil and form chromatin. Spindle fibers break down.
Cleavage furrow forms and separates animal cells into two identical daughter cells.
In plants a cell plate forms that divides the cell into two and then and new wall forms around it.
chromatin that has condensed into short thick rods
a chromosome attached to its identical copy
DNA wrapped around histone proteins, appears as threads inside the nucleus
the protein that holds two sister chromatids together
the protein chains that attach to the centromeres and move the chromosomes to opposite ends of the cel
organelles in animal cells that make the spindle fibers
abnormal cell growth
process of cell reproduction in prokaryotes creates two identical cells
