Also responsible for cell reproduction system via division into 2. Too much damage over time wears down the cell"s natural repair process but this can be avoided with b12 and folic acid. The cytoplasm: suspended structures , all vital chemicals necessary to maintaining cell function. Dna: code for everything, double helix formation, one strand from each parent. Chromosomes: 23-non identical chromosomes contain 25,000 genes, made of dna and proteins. Genes: when a gene is turned on it makes the code readable and creates a certain amount of proteins at which point the gene is turned off. Gene expression: enables certain proteins to be produced, gene contains recipe for protein.
