Document Summary

Nucleotides have a nitrogenous base and a 5 carbon sugar and a phosphate group. Purines have 5 rings connected to 6 rings. Pyrimidine have a sing ring of 4 carbon atoms and 2 nitrogen atoms. A phosphodiester linkage bonds 2 nucleotides together. Watson & crick are known to be the founders of dna, but they just copied rosalind. Rna structure rather looks like a hairpin loops also known as trna (please search that pic up for your info) Nucleotides assemble into polymers via the formation of phosphodiester bonds between the 5 carbon of one nucleotide"s sugar and the 3 carbon of another nucleotide"s sugar. The phosphate functional group is part of this linkage. These covalent bonds hold together the sugar-phosphate backbone of the polynucleotide. Chapter 13 - already covered just added the summary. Prokaryotic cells are much smaller and do not contain a nucleus or membrane-bound organelles.
