What is Binary Fission? The results in two nearly equal, independent cells.
What is Cell Division? The process by which cells divides into two or more cells.
What is Interphase? The stage of a cell immediately following the completion of cell division.
What is Mitosis? The process in cell division in which the nucleus divides to produce two new nuclei, each having the having the same number and type of chromosomes as the original.
What is Cell Cycle? The series of events that takes place in a cell leading to its division and duplication.
What is Chromosome? A structure in all living cels that carries the genes that determine heredity.
What is Cytokyinesis? The cytoplasmic division of a cell at the end of mitosis.
What is Genetic Material? The material found in cells that contains the genetic information of living organisms.

What is Anaphase? The stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle.
What is Telophase? The final phase of cell division in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
What is Spindle Fibers? The structure that separates the chromosomes into the daughter cells.
What is Interphase? The period between cell divisions when growth and replacement occur in preparation for the next division.
