#Section 3: Genetics, Cellular and Molecular Biology

  1. nucleosomes both from the parental DNA and newly assembled.

  2. nucleosomes, each with histones both from the parental nucleosomes and newly synthesized.

  3. nucleosomes either all newly synthesized or all from the parental strand.

  4. a random combination of both nucleosomes and individual histones, both newly synthesized and from the parental strands.

A fermentation slurry containing Streptomyces kanamyceticus cells is filtered using a continuous rotary vacuum filter. 120 kg h- 1 slurry is fed to the filter; 1 kg slurry contains 60 g cell solids. To improve filtration rates, particles of diatomaceous-earth filter aid are added at a rate of 10 kg h- 1. The concentration of kanamycin in the slurry is 0.05% by weight. Liquid filtrate is collected at a rate of 112 kg h-1; the concentration of kanamycin in the filtrate is 0.045% (w/w). Filter cake containing cells and filter aid is continuously removed from the filter cloth.
 What percentage liquid is the filter cake?

If the concentration of kanamycin in the filter-cake liquid is the same as in the filtrate, how much kanamycin is absorbed per kg filter aid?.,..... 10-4
