Imagine that you've isolated a yeast mutant that contains histones resistant to acetylation. What phenotype would you predict for this mutant?

#Section 3: Genetics, Cellular and Molecular Biology
  1. The mutant will grow rapidly.

  2. The mutant will require galactose for growth.

  3. The mutant will show decreased levels of gene expression.

  4. The mutant will show increased levels of gene expression.

E. coli was continuously cultured in a continuous stirred tank fermenter with a working volume of 1.0 I by chemostat. A medium containing 4.0 g1-1 of glucose as a carbon source was fed to the fermenter at a constant flow rate of 0.5 I h-1, and the glucose concentration in the output stream was 0.20 g1-1, The cell yield with respect to glucose YxS was 0.42 g dry cells per gram glucose. Determine the cell concentration in the output stream
