In experiments conducted by Singer and Fraenkel-Conrat, hybrid versions of tobacco mosaic virus were produced using RNA and protein from the hybrids. derived from different viral strains. Progeny viruses of the hybrids showed inheritance of O lipids O carbohydrates O proteins ORNA O DNA

3) It is now 2085 and the world is experiencing another pandemic viral infection. The scientist that discovers the virus, purifies out the genetic information and learns that it has a sequence that is: 26% Cytosine 21% Adenine 28% Uracil and 25% Guanine What sort of genetic information does this new virus have? DNA or RNA? Single or Double Stranded? Explain how you know!

A bacterial cell receives a new gene contained on a plasmid exchanged through the formation of a sex pilus. This exchange of DNA would best be described as O Horizontal Gene Transfer Transduction Conjugation O Transformation

A THF -wwwwwwwwww DHF -wwwwwww DNA mRNA 30 B с 50 30 Ribosomes 50 30 D E 45. If the microbe uses target modification to avoid Streptomycin, then which structure above should it focus on modifying?

You infect bacterial cells with an experimental, bacteriophage which consists of the T4 protein coat and T2 phage DNA any new phages produced would produced

A bacteriophage has inserted its DNA into a bacterial host and replicated as a part of the host’s genome for several generations as the host reproduces.  For this virus to assemble more infectious viral particles, what must it do?   Switch to the lysogenic cycle of replication Switch to the vicious cycle of replication Purposefully mutate its own genes Switch to the lytic cycle of replication

The Influenza virus is a (-)ss RNA virus that _________ bring its own RNA Polymerase into the host cell with it.  This virus will gain entry into host cells through _____________ by using the Hemagglutinin Spike protein present on its envelope, which allows the viral envelope to merge with the host cell membrane.   Select one: a.Does not need to / Fusion b.None of the Above c.Needs to / Membrane Fusion  d.Does not need to / Endocytosis  e.Needs to / Endocytosis
