nucleotides and nucleic acids

Question 1

what are nucelic acids

Answer 1

polymers of nucleotides- storage of genetic info, transmission of genetic info, processing of genetic info, protein synth

Question 2

what function have nucleotides in monomer form

Answer 2

energy for metabolism, enzyme cofactors, signal transduction

Question 3

what are the elements of a nucleotide

Answer 3

nitrigenous base, pentose and phosphate

Question 4

nucleoside componenets

Answer 4

nitrogenous base and pentose

Question 5

do purines or pyrimidiens have double ring structure

Answer 5

purines (adenine and guanine)

Question 6

is the phosphate group on nucelotides charged

Answer 6

neg charge at neutral pH

Question 7

where does phosphate group attach to in nucleotide

Answer 7

5’ position

Question 8

what is the B-N-glycosidic bond

Answer 8

the bond that joins the pentose ring to the nitrogenous base- at pos N1 in pyrimidines and pos N9 in purines

Question 9

describe rotation around the N glycosidic bond

Answer 9

relatively free rotation can occur in free nucleotides

Answer 10

normal B DNA

Question 11

what is a tautomer

Answer 11

structureal isomers that differe in location of protons
