A 
serine
threonine
tyrosine
asparagine
cysteine
glutamine
22

26
Q

this is a secondary structure that refers to how neighboring alpha helices, beta sheets, and beta turns are oriented to each other?

A

motif

greek key
beta meander

27
Q

A

carbon 2

deoxyribose

28
Q

this regulatory enzyme commits to ribose to be made into nucleotides or deoxynucleotides?

A

ribose phosphate pyrophosphokinase preps carbon 1 for synthesis of purine or pyrimidine

produces PRPP(5 phospho alpha, D ribose 1 pyrophosphate) from ribose 5 PO4

what do purines make, IMP or UMP? what do pyrimidines make, IMP or UMP?

A

IMP

UMP

33

A

uric acid

37
Q

this enzyme inhibits xanthine oxidase, used to treat gout?

A

allopurinol

38
Q

rRNA

tRNA

46
Q

RNA polymerase directionality?

A

reads 3-5
writes 5-3

unlike DNA polymerase, no exonuclease

47
