Document Summary
Chapter 2: the genetic and evolutionary roots of behavior. Red blood cells contain large amounts of protein called hemoglobin. Hemoglobin picks up oxygen when red blood cells pass through the lungs and then drops off the oxygen when cells pass through the other body"s tissues. Each cell consists of a nucleus the biological control center of the cell. In the nucleus, there are chromosomes complex structures in the nucleus of each cell that contain the genes. A human has 46 chromosomes in 23 pairs. Each chromosome has single dna the molecule that is constituent of genes. It provides a set of detailed instructions for making proteins that give each cell its shape and for making the proteins called enzymes that govern cell functioning. The rungs of the dna ladder are made up of adenine, thymine, cytosine, and guanine. Dna enables molecules to carry instructions for building proteins.
