PPT-Chromosome Structure Review

Gene DNA is a large molecule broken down into hereditary units called genes DNA is organized amp packaged into chromosomes Chromosome DNA wound or coiled tightly around proteins histones. The bacterial chromosome is a double-stranded, circular DNA molecule associated with a small amount of protein. Eukaryotic chromosomes have linear DNA molecules associated with a large amount of protein. 10 Edition. Chapter . 8. DNA Structure and Function. Copyright . © 2018 . Cengage. Learning.
