- Fill in the blanks. The parentheses after each blank represent the choices for the blank. Scientists already knew that a special type of virus called a bacteriophage inserts genetic information into a bacterial cell in order to force the bacterial cell to make more bacteriophage viruses. What scientists did not know, however, was whether that genetic information is carried by the _____________ (proteins, DNA) covering the outside of the bacteriophage virus or by the _____________ (proteins, DNA) inside the bacteriophage virus.Fill in the blanks.

- given below is a small slice of a large sequence of protein taken from ORF1a polyprotein of Severe acute respiratory syndrome coronavirus 2 (isolate: wuhan-1). Convert the following sequence into protein strand using one letter code: 5'-ACCAACCAACTTTCGATCTCTTGTAGATCT-3'3 types of common coronavirus tests (RT-PCR for viral RNA with Taqman detection, lateral flow antibody tests, and lateral flow antigen tests) have been examined. a) The RT-PCR with Taqman detection is used to test for viral RNA in univeristy laboratory for testing saliva samples. Why do you think a univerisity chose chose this test to screen students/faculty/staff for Covid-19 on a regular basis? Explain your answer by discussing advantages/disadvantages of the test. b)An antigen test was used to screen students in when they arrived on campus. Why do you think a univeristy chose this test for this purpose? What are advantages and disadvantages of this test? c)Do you think the RT-PCR test with Taqman detection for viral RNA is best test for regular screening? Justify your answer.You are a virologist studying a newly isolated viral strain and have sequenced its genome. You find that the genome contains 25% A, 55% G, 20% C, and 10% U. Which of the following conclusions is likely correct? This is a single-stranded RNA virus This is a single-stranded DNA virus This is a double-stranded RNA virus This is a double-stranded DNA virus No conclusions can be drawn from this information
- You are studying a new virus with a DNA genome of 12 Kb. It can synthesize DNA at a rate of 400 nucleotides per second. If the virus uses rolling-circle replication, how long will it take to replicate its genome? Answer only for the first strand; ignore replication along the displaced strand. O 7.5 seconds O 15 seconds O 30 seconds O 1 minute O 2 minutescomputer applications can be used to translate viral genomic sequence just as you did manually, however computer applications cannot tell you the meaning or significance of mutation. based on your experience what might be a disadvantage in using computer applications to compare new strains of the virus that causes COVID19. please asap dont copy from any other site i already have that answerProtein vaccines include only the parts (i.e. a protein) of a virus that best stimulate your immune system. This type of COVID-19 vaccine contains harmless S proteins. Once your immune system recognizes the S proteins, it creates antibodies and defensive white blood cells. If you later become infected with the COVID-19 virus, the antibodies will fight the virus. Assume that you work in a project for development of such vaccine against COVID-19. The vaccine contains S Protein and your job includes isolation of pure S Protein from the virus determination of charge on the protein (or pI) determination of molecular mass revealing three dimensional (3-D) structure of the protein How would you determine the pI of the protein?

The ordinate (i.e., 'y-axis') represents values for the C or G nucleotide base proportion in sequences (or, in this case, genomes).ii. Influenza viruses that infected birds or moved from birds to humans without spreading are characterised by higher A + U content relative to influenza viruses that infected humans for long time periods.iii. Influenza viruses adapted to human hosts are characterised by lower G + C content relative to influenza viruses that infected birds or moved from birds to humans without spreading. iv. Human and swine influenza A H1N1 strains evolved from a birdlike G + C state to a humanlike G + C state since 1918. v. Data such as those depicted in the figure have been interpreted as evidence that the 1918 influenza virus strain originated from a bird influenza virus population.
