  • MOLECULES OF LIFE
    • Cell strucute
      • mitochondria in cytoplasm depends on activity. respiration in mito, more activity = more respiration = more mitochondria.
      • Rymosomes - in cytoplasm, site of protein synthesis
    • DNA and the genetic code
      • Nucleus contains genes - section of a chromosome made of DNA - codes for a particular protein
      • DNA = two strands coiled to make a double helix. Four different bases withe cross links between the strands formed by pairs of bases - each gene different sequence
    • Discovering the structure of DNA
      • Watstion + Crick found out structure through other scientist data: X rays of data wound in double helix and data indidcating bases in pairs
      • Worked out structue in 1953, received Nobel prize in 1962 delays because discoveries needed to be checked
