During the production of gametes, sister chromatids are separated as the individual chromosomes move to opposite ends of the cell. the nuclear membrane is now forming around each haploid set of chromosomes. which of the following is the best conclusion you can make about the life cycle of this cell?

the cell will rejoin the chromatids, and interphase ii will begin.

the cell is in interphase ii and will enter prophase ii next.

the cell is in telophase ii, and cytokinesis will occur next.

the cell will undergo dna replication in order to become diploid again.

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.
