Base analysis of DNA shows it to have 24 mole percent of cytosine (moles per 100 moles total nucleotide). Based on this information, write below the percentages of the remaining bases (Guanine, Adenine and Thymine):

Calculate the velocity of a reaction of a substrate at 20 mM if Vmax = 100 μmol/mL‧sec and Km = 2 mM 

Below is a table showing the values of Km of two enzymes vs different carbohydrates as their substrate. Based on what you know about the meaning of Km, evaluate the two enzymes’ affinity and specificity towards those carbohydrates.
