Document Summary
Chemical context of life- introduction to dna and genetics. Only have to deal with 11 or 12 elements. What"s the world made of: as world went on, we got more complicated ideas, essentially just atoms/elements. Particle accelerators make the rest of elements other than 92 naturally-occurring ones. Nitrogen deficiency- corn doesn"t grow as much. Goiter (iodine deficiency)- thyroid condition- swollen throat. Standard model- just for fun- particle physics- looking for higgs boson (gives particle mass) Molecule- two or more atoms sharing electrons. Covalent bond- most important for organic chemistry. Chemistry is about making and breaking covalent bonds (restriction enzymes, etc. ) H of one molecule and o of other bond- not sharing electrons, not stealing them either: important in dna and protein structure. 2 strands of dna joined by hydrogen bonds: h and o/n, usually. Molecular structure explains function: structure of dna allows it to encode your information, important!
