| a form of asexual reproduction in single-cell organisms by which one cell divides into two cells that are the same size | binary fission |
| a segment of DNA that is located in a chromosome and that codes for a specific hereditary information | gene |
| in a eukaryotic cell one of the sructures in the neucleus that are made up of DNA and protien in prokaryotic main ring of DNA | chromsome |
| one of two strands of chromosomes that became visible in meiosis and mitosis | chromatids |
| the region of the chromosome that holds two sister chromatids during mitosis | centromere |
| chromosomes that have the same sequence of genes that have same stucture and that pair together during mitosis | homologus chromosomes |
| a cell that contains two haploid sets of chromosomes | diploid |
| describes a cell, neuclus, or organisms that has only one set of unpaired chromosomes | haploid |
| the cell that results form the fusion of gametes (sperm, egg) fertelized egg | zygote |
| anuy chromosome tyhat is not a sex chromosome | autosome |
| one of the pair of chromosomes that determine the sex of an individual | sex chromosomes |
| an array of the chormosmes found in and individual metaphase of mitosis and arranged in homolgus and in order of diminishing size | karyotype |
| the life cycle of a cell (in eukaryotes) it consists of a cell growth period in wich DNA is synthesized and a cell division period in which mitosis takes place | cell cycle |
| a period between two mitotic divisions during which a cell grows, copeis its DNA, and synesizes protiens | interphase |
| a eukaryotic cells, a process of cells division that forms two nuclei, each with same number of chromosomes | mitosis |
| the division of the cytoplasma of a cell, follows meosis and mitosis | cytokinesis |
| a tumor in which the cells begin dividing at an uncontrolled rate and become masive | cancer |
