Answer   Chromosomes are located in the nucleus of a cell in eukaryotes. In prokaryotes (which lack a cell nucleus) chromosomes are circular in shape usually found â¦ attached to the plasmid membrane.
Chromosomes [chromosome: One of the rod shaped bodies found in the nucleus of cells that contain genetic information (DNA).] are threadlike structures found in the nucleus of most cells (remember red blood cells have no nucleus and so these are not produced by mitosis).ll the cells in the body of a particular species contain the same number of chromosomes. Cell division, or mitosis, is the method of increasing the number of cells. Single celled organisms can reproduce in this way to make new organisms.
