Terms in this set (20)
Chromosomes are copied. Chromosomes appear as threadlike coils at the start, but each chromosome and its copy change to sister chromatids at the end of this phase.
Mitosis begins as centrioles appear and begin to move to opposite ends of the cell. Spindle fibers form between the poles.
Chromatids attache to the spindle fibers. The chromosomes line up along the middle of the cell.
Chromatids separate and begin to move to opposite ends of the cell, pulled along by the spindle fibers
Two new nuclei form. Chromosomes appear as chromatin. Mitosis ends.
Cell membrane moves inward to create two daughter cells - each with its own nucleus with identical chromosome.
The most condensed and constricted region of a chromosome, to which the spindle fiber is attached during mitosis.
Cell division in which the nucleus divides into two nuclei containing the same number of chromosomes with an end result of two identical cells.
A part of the cell containing DNA and RNA and responsible for growth and reproduction.
Special microtubules made of proteins which connect to centromeres and pull apart chromosomes..
Coiled structure of DNA and protein that forms in the cell nucleus during cell division.
Identical copies of a chromosome.
The simple cell division in which one cell splits into two; used by bacteria.
Found in the life of a eukaryote cell. It consists of chromosome duplication, mitosis, and cytokinesis
A single, twisted thread of DNA used to direct all cell activities during interphase.
"Body" cells; all cells except sex cells (egg and sperm), somatic cells carry a full set of chromosomes (i.e., 46 chromosomes in humans).
Original cell from which new cells are formed.
The term used to describe the two new, identical, cells which form at the end of cell division.
A structure formed in dividing plant cells during telophase.
Opposite ends of a cell. Chromatids move toward the poles during anaphase.
