Gene Facts



  • Genes are the body’s chemical instructions for your entire life – for growing up, surviving, having children and, perhaps, even for dying.
  • Individual genes are instructions to make particular proteins – the body’s building-block molecules.
  • Small sets of genes control features such as the color of your hair or your eyes, or create a particular body process such as digesting fat from food.
  • Each of your body cells (except egg and sperm cells) carries identical sets of genes. This is because all your cells were made by other cells splitting in two, starting with the original egg cell in your mother.
  • Your genes are a mixture – half come from your mother and half from your father (see chromosomes). But none of your brothers or sisters will get the same mix, unless you arc identical twins.
  • Genes make us unique – making us tall or short, fair or dark, brilliant dancers or speakers, healthy or likely to get particular illnesses, and so on.
  • Genes are sections of DNA JIM ISM 117.1.01MO,..791.UOVIIVIIIIIII – a microscopically tiny ..,FASCINATING FACT ,. molecule inside each cell. There are more than 30,000 individual
  • DNA is shaped in a double genes inside every single cell of your body. helix with linking bars, like a twisted rope ladder.
  • The bars of DNA are four special chemicals called bases – guanine, adenine, cytosine and thymine.
  • The bases in DNA arc set in groups of three called codons, and the order of the bases in each codon varies to provide a chemical code for the cell to make a particular amino acid.
