Step by step
Solved in 2 steps
- Many patients become resistant to HIV protease inhibitors with the passage of time, owing to mutations in the HIV gene that encodes the protease. Mutations are not found in the aspartate residue that interacts with the drugs. Why not?Why are structural analogs of sugar molecules (such as Oseltamivir and zanamivir) effective in treatment of influenza-virus infection?Why are proteins synthesised from spirulina called single cell anemia?
- Two possible point mutations are the substitution of lysine for leucine or the substitution of serine for threonine. Which is likely to be more serious and why?When Avery and his colleagues had obtained what was concluded to be the transforming factor from the IIIS virulent cells, they treated the fraction with proteases, RNase, and DNase, followed in each case by the assay for retention or loss of transforming ability. What were the purpose and results of these experiments? What conclusions were drawn?In 1994, the U.S. Public Health Service identified “10 Essential Public Health Services.” For each of the ten, please briefly describe a specific activity that has been used in the response to COVID-19.
