CHROMOSOMES are LONG MOLECULES OF DNA	A GENE is a SHORT LENGTH of a CHROMOSOME
GENES control CHARACTERISTICS, e.g hair and eye colour	There are different versions of GENE, different versions of the same GENE are called ALLELES
Each GENE is a CODE for making a certain protein	Some PROTEINS are STRUCTURAL, these are found in skin, hair, blood and the cytoplasm
COLLAGEN is a PROTEIN found in tendons, bones and cartilage	Some PROTEINS are FUNCTIONAL, ENZYMES are proteins that help with digestion
