Found in almost every organism, DNA provides instructions for creating the myriad of proteins that build an organism. A gene is a stretch of DNA which has the code to produce a particular protein and is passed on to the next generation during reproduction or to new cells during replication. Mistakes in the copying of genes or damage to the DNA code are called mutations and can lead to altered traits, which may then be selected for and lead to the evolution of a species.
