Which of the following statements is/are correct regarding BLAST ? 

#Section 7: Recombinant DNA technology and Other Tools in Biotechnology
  1. The lower the E-value, the less likely the database match is a result of random chance and therefore the more significant the match is.
  2. If E > 10, the sequences under consideration are either unrelated or related by extremely distant relationships.
  3. BLAST score increase lower sequence similarity.
  4. If E is between 0.01 and 1e − 50, the match can be considered a result of homology.

A bacterial culture having a specific oxygen uptake rate of 5 mmol O2 (g DCW)−1 h−1 is being grown aerobically in a fed-batch reactor. The maximum value of the volumetric oxygen transfer coefficient is 0.18 s−1 for the stirred tank bioreactor and the critical dissolved oxygen concentration is 20% of the saturation concentration (8 mg L−1). The maximum density to which the cells can be grown in the fed-batch process, without the growth being limited by oxygen transfer, is approximately

A urine sample with more than 100,000 organisms is considered indicative of infection. A urine sample containing 5,000 bacteria, with a generation time of 30 minutes, sits for 3 hours before finally being assayed. How many bacteria will then be present within the sample?
