A protein with this many strands contains lots of hydroxyproline, which means Vitamin C is needed to make it.
This many amino acids are used for catalysis at the active site of enzymes like chymotrypsin. The antioxidant glutathione is made of this many amino acids. DNA has this number of natural conformations. A protein with this many strands contains lots of hydroxyproline, which means Vitamin C is needed to make it. The end of (*) mRNA denoted "this number-prime" is given a poly-A tail. Collagen is made of this many strands. RNA and DNA share this number of nucleobases, since thymine is swapped out for uracil. ATP has this many phosphate groups. For 10 points, give the number of nucleotides in a codon, which is one more than the number of helices in DNA.
This many amino acids are used for catalysis at the active site of enzymes like chymotrypsin.
