Chromosomes and Cell division
Almost all genes of a Eukaryotic cell are located in the cell nucleus.
Genetic materials exists in long thin strands too small to be seen.
These fibers consist of chromatin, which is a combination of DNA and Protein molecules.
See Figure 9-3The number of chromosomes an organism has varies. For example, humans have ________ also know as _________ pairs.
