Compared with DNA polymerase, reverse transcriptase: 

#SCPH01 Biochemistry
  1. does not require a primer to initiate synthesis.

  2. introduces no errors into genetic material because it synthesizes RNA, not DNA.

  3. makes fewer errors in synthesizing a complementary polynucleotide.

  4. makes more errors because it lacks the 3'  5' proofreading exonuclease activity

Pseudomonas methylotrophus is used to produce single-cell protein from methanol in a 1000 m3 pressure-cycle airlift fermenter. The biomass yield from substrate is 0.41 g g- 1, KS is 0.7 mg l- 1, and the maximum specific growth rate is 0.44 h- 1. The medium contains 4% (w/v) methanol. A substrate conversion of 98% is desirable. The reactor may be operated either in batch or continuous mode. If operated in batch, an inoculum of 0.01% (w/v) is used and the downtime between batches is 20 h. If operated continuously, a downtime of 25 d is expected per year. Neglecting maintenance requirements, compare the annual biomass production from batch and continuous reactors?
