3 Q1)Give two examples of organic compounds? Sugar, Starch
4 Inorganic compounds Don’t contain carbon Don’t come from living things Exceptions: Carbon dioxide, Carbon monoxide
5 Q2) Give 2 examples of inorganic molecules Water, Salt
6 Unique bonding properties of carbon Carbon has four electrons in its outer shellCarbon can form 4 covalent bondsCarbon can form complex molecules because of its ability to form 4 bonds at the same time
7 Chemistry of carbon Carbon can form Single covalent bonds Shares 1 electron with one other atom.Double covalent bondsShares 2 electrons with one other atomTriple covalent bonds (rare)Shares 3 electrons with one other atom (See examples of these bonds on the bottom of page 49)
8 Functional groups Common parts used molecule building Hydroxyl -OHCarboxyl-COOHAmino-NH2
57 Two types of nucleic acids and their uses: Deoxyribonucleic AcidDNAStores genetic information and passes it on to the next generationRibonucleic AcidRNATakes information and uses it to make proteins
58 The information is stored in bases The differences in the nucleotides is in the bases.The order of these bases makes up the genetic CODE.
59 DNA BasesThere are four bases used in DNA Cytosine (C), Thymine (T) Adenine (A), Guanine (G)
60 RNA Bases There are four bases used in RNA Cytosine (C), Uracil (U) Adenine (A), Guanine (G)Thymine is replaced by Uracil in RNA
