Nucleic acids Flashcards
polymers?
nucleic acids (DNA and RNA specifically)
monomers?
nucleotides
nucleotide subunits?
pentose sugar ((deoxy(ribose)
phosphate group
nitrogenous base
describe the bases
purines have 2 rings - adenine and guanine
pyrimidines have 1 ring - uracil, thymine, cytosine
how are polymers of nucleic acids formed
OH of phosphate group and OH of pentose sugar undergo condensation reaction to form phosphodiester bonds
monomers of DNA?
deoxyribonucleotides
naming DNA mnomers?
deoxycytosine monophosphate etc
describe the structure of DNA polymer
double helix - sugar phosphate backbone wrapping arroud hydrophobic bases
major groove and minor groove
the names of the strands within DNA?
sense strand
nonsense strand
how do we write DNA?
ALWAYS from 5’->3’ direction
main differneces between DNA and RNA
number of strands
type of sugar
the bases
