Document Summary
You don"t need to know structure and all of the bases and how their differences affect their h-bonding patterns: purine, pyrimidine: cytosine, thymine, uracil. (uracil can be found in dna, but is then removed) Uracil is attracted to adenine: adenine, guanine, numbers differentiate numbers from the sugar. Oh ribose, only h on deoxy. Can be found in rna: metabolites in purine synthesis degrade. There would be lots of degredation of purines in: During cell death: mrna degradation in normal cells. Another cause of degradation is chemotherapy: doesint always mean cancer, but killing cells. Urine is another degradation product: if concentration is high it will crystalize. Gout: peoples joints becoming very sore: urice acid builds up in the joints and becomes solid. Can be a side effect of chemotherapy. A ribose and adenine nucleoside = adenosine. what are the others called? (uracil&ribose) Dump is called deoxyuridate or dexuridine monophosphate. When dna is pure absorbs light maximally at 280nm (proteins)
