| Histones | help maintain the shape of the chromosome and aid in the tight packing of DNA. |
| Chromatid | half of a chromosome form as the DNA makes a copy of itself before cell division. |
| Centromere | The constricted area of each chromatid. Holds the two chromatids together until they separate during cell division |
| Homologous chromosomes | two copies of each autosome they are the same size and shape and carry genes for the same traits |
| Diploid cells | have 2 sets of chromosomes |
| Haploid cells | have only 1 set of chromosomes Human sperm and eggs cells. |
| Somatic Cells | body cells |
| Gametes | sex cells |
| Chromatin | unwound DNA found in the nucleus of the cell during interphase |
| Centrioles | structure found in animal cells that produce the spindle fibers |
