| Nucleic acids allow the transfer of genetic information from generation to generation by means of DNA replication.
| | See [[Nucleic_acids|nucleic acids]] |
| | |
| There are two types of nucleic acid:
| |
| | |
| #DNA
| |
| #RNA, (appears in several forms)
| |
| | |
| Nucleic acids have 3 main features:
| |
| | |
| #Nitrogenous base.
| |
| #5 Carbon sugar.
| |
| #Phosphate group.
| |
| | |
| The Nitrogenous group has 4 variants in DNA, these are:
| |
| | |
| #Adenine (A)
| |
| #Thymine (T)
| |
| #Guanine (G)
| |
| #Cytosine (C)
| |
| | |
| RNA substitutes Uracil for Thymine.
| |
| | |
| Adenine is complementary to Thymine and Guanine is complementary the Cytosine. Hydrogen bonds form between complementary bases of different nucleic acids. 2 hydrogen bonds form between A and T and 3 between G and C.
| |
| | |
| Covalent phosphodiester bonds form between the phosphate groups of neighbouring nucleic acids <ref>http://biology.about.com/od/molecularbiology/a/nucleicacids.htm</ref>.<br>
