Which of the following correctly defines translation?

A.) the making of a polypeptide with a specified order of amino acids using an RNA molecule to provide the sequence information

B.) the making of a polypeptide with a specified order of amino acids using a DNA molecule to provide the sequence information

C.) the making of an RNA molecule from a DNA strand by pairing of bases of RNA nucleotides with the complementary bases in DNA

D.) the making of a new DNA molecule by pairing of bases of DNA nucleotides with complementary bases in an existing DNA molecule

Penicillin is hydrolyzed and thereby rendered inactive by penicillinase (also known as β-lactamase), an enzyme present in some resistant bacteria. the mass of this enzyme in staphylococcus aureus is 29.6 kd. the amount of penicillin hydrolyzed in 1 minute in a 10-ml solution containing 10-9 g of purified penicillinase was measured as a function of the concentration of penicillin. assume that the concentration of penicillin does not change appreciably during the assay. penicillin(μm) amount hydrolyzed(nmol) 1 0.11 3 0.25 5 0.34 10 0.45 30 0.58 50 0.61 (a) plot v0 versus [s] and 1/v0 versus 1/[s] for these data. does penicillinase appear to obey michaelis-menten kinetics? if so, what is the value of km? (b) what is the value of vmax? (c) what is the turnover number of penicillinase under these experimental conditions? assume one active site per enzyme molecule.
