- An experimental drug therapy to treat patients with antibiotic-resistant bacteria involves introduction of a highly specific bacteriophage to the infected patient's bloodstream. Which of the following bacteriophage types would be the LEAST useful for this therapy? a. a lytic bacteriophage b. An enveloped virus c. An RNA virus d. a lysogenic bacteriophagearrow_forwardWhy not just inject the double-stranded cDNA that codes for the spike protein of the virus? What additional step or steps would you need to use to get the human muscle cells to produce the spike protein if the cDNA was injected to serve as the virus? The new Covid19 vaccine produced by two companies (Pfizer, Moderna) uses mRNA coding for part of the spike protein of the virus. The virus uses the spike protein to invade human cells where it replicates. Is it surprising that the mRNA must be stabilized with chemicals that need ultra-cold or frozen storage to protect the mRNA from degradation before it causes human muscle cells to make the spike protein?arrow_forwardThe Baltimore Classification Scheme is fundamentally based on _____. a. the synthesis of viral proteins b. the type of viral genome c. the importance of viral mRNA during the replication cycle d. all answers are correctarrow_forward

Would this genetic material contain equal amounts of A andT and equal amounts of G and C?arrow_forwardThere is a big debate if viruses are alive or not. Either way, look at the list below and pick out the accurate statements. A. Can only reproduce/replicate in a living cell. B. They have a protein coat surrounding and protecting the nucleic acid. C.
