| Summary |
When you look into a microscope at a cell you will see a large circle near the center of the cell. This is the nucleus and holds the genetic material, or, chromosomes. Chromosomes are made of long strands of DNA (deoxyribonucleic acid) and, therefore genes. Humans have 46 chromosomes, the focus of study in this book. First, we will explore chromosomal morphology, then how they are reproduced (during cell division), and the normal and abnormal condition of chromosomes. In this book, we will explore the biology of cells and their one important organelle: the nucleus. Within that organelle are the chromosomes, long strands of protein that are made of DNA and control our heredity |
