Link DNA DNA holds the instructions needed for a living organism to grow and live. DNA stands for deoxyribonucleic acid. The DNA alphabet is ACGT. ( Guanine, Cytosine , Adenine and Thymine.) The special rules by which these alphabet pieces bond together are that A only goes with T, and C only goes with G. Genes Genes are the basic units of inheritance. They are the instruction manuals for the body. The directions for building proteins to function. Genes are made of chunks of DNA . Humans have 25,000 genes. Proteins contain these instructions for building. Genes tell the body three important things: How long the protein should be. How much protein to make. Exactly when to make it. Chromosomes A chromosome is a package for DNA. In other words, chromosomes are
