Document Summary
All of human development has a genetic basis: genome: the master blueprint that provides detailed instructions for everything from how to grow a gallbladder to where a nose gets placed on a face. The genome provides options for a cell, but the environment determines what it will become: chromosomes: structures within the cell body made up of dna (deoxyribonucleic acid), segments of which comprise individual genes. In a typical human, nearly every cell contains 23 pairs of chromosomes, one of each pair coming from its parents: genes: segments of dna that help determine the characteristics of an organism. Each gene specifies an exact instruction to manufacture a distinct polypeptide, which make up proteins. Proteins are the basic chemicals that make up the structure of cells and direct their. Heredity involves passing along genes through reproduction activities: the first clues to the mechanisms responsible for heredity were discovered by the monk.
