Document Summary

Major functions of dna and rna: dna: genetic make up. Information that can be read to create a living organism: rna. Mrna messenger rna, gives information to code for proteins srna: splicing. Ribose: 5 carbon sugar, the basis for ribonucleic acids, add a base to ribose = ribonucleoside, base + sugar = nucleoside, n-glyosidic bond. Beta configuration (always: prime indicates atoms in the sugar e(cid:454). (cid:1005)". A ribonucleoside: base and a sugar cytidine monophosphate. = a nucleoside monophosphate ribonucleoside + one phosphate. = a nucleoside triphosphate ribonucleoside + three phosphate: can have diphosphate, typically, only goes up to 3. Nucleotide= sugar, base and at least one phosphate.
