CHEM 351 Lecture Notes - Lecture 31: Adenine, Hydrolysis, Hydrophile
Document Summary
Electron carriers nad(cofactor in redox rexns) and fadh2 (derivative of nucleotides) Catalytically ribozymes (overlap with protein)/ functional rna and rna that turns into proteins. Basic structure- sugar (pentose deoxyribose or ribose), phosphate group, nitrogenous base. Phosphate group always attached to 5" end of sugar in poly. Uv absorbance: maximum peak at 260 nm (250-270 nm) Excited states decay rapidly via radiation-less transition allowing for protection of nucleic acids and nucleotides from photons of light and allow to study them. Nucleotide: phosphorylate (and indicate how many phosphates attached) Epigentic marker- mod of genetic material after it has been made (can be removed at any time) Modified throughout life unlike genetic info. (consistent except for replication errors) Purpose: to identify foreign dna/ different methylation pattern / also for repairing dna and id newly synthesized dna. Thymidine methylated form of uracil ( to make it more stable) Inosine: base pairs with most of other nucleotides (used in trna of anticodon)
