Genes: Our Biological Blueprint 1. Describe the composition and physical location of genes. When egg and sperm unite, the 23 chromosomes from the egg pair with the 23 chromosomes from the sperm. Each chromosome is composed of a coiled chain of a molecule called DNA (deoxyribonucleic acid). DNA is in turn composed of thousands of genes, the biochemical units of heredity. They provide the blueprint for protein molecules, the building blocks of our physical and behavioral development. Our genes are composed of biochemical letters called nucleotides. The Human Genome project has discovered the common sequence of nearly all the three billion letters within our DNA and thus is close to having the complete instructions for making a human. Evolutionary Psychology: Explaining Universal Behaviors 2. Discuss the impact of evolutionary history on genetically predisposed behavior tendencies.
