Chromosomes: Their Structure, Function, and Medical Importance

Chromosome Structure - US Natl Library of MedicineChromosomes are threadlike strands of DNA with associated proteins found in the nuclei of eukaryotic cells. The collections of chromosomes in plants, animals, and humans carry two complete sets of identification information. The duplicate set allows for cell division and reproduction. Genes on chromosomes can be defective in a number of ways and are closely related to a number of genetically induced disorders, including Down Syndrome, Tay-Sachs Disease, Huntington’s Disease, Klinefelter Syndrome, and Sickle Cell Anemia. Learn more about the many ways chromosomes impact our lives, and the scientists who study them, in articles provided by informed Bright Hub contributors.
