If I am making 500ml of a solution with 0.625ml ITS, 0.0035ml Linoleic acid, 20ml Nu-serum, 0.75g BSA, and DMEM:F12 as my solvent, how best would I make this solution and what tools would be the most accurate to use?

Which step(s) occur in the lysogenic replication cycle of temperate phage but does not occur in the lytic replication cycle? O adsorption O biosynthesis O assembly O release O formation of prophage and lysogen

Following the infection of healthy tobacco leaves by reconstitutedviruses, what two characteristics did Fraenkel-Conrat andSinger analyze? Explain how their results were consistent withthe idea that the RNA of TMV is responsible for the traits ofthe virus.

which of the following is NOT a mechanism by which viruses can damage the human body (ie- harm us)? causes our viral infections may lead to the release of too much cytokines/chemical signals O may cause our defenses/immune system to over-react Othey produce and release toxins O may cause cancer Otheir replication (life cycle) destroys our cells

Rift Valley Fever (RVF) is a vector borne disease that infects people. Most cases are mild, but a sometimes it causes high fevers, seizures, and brain swelling. RVF epidemics have occurred at 5-10 yr intervals in drier areas of eastern Africa, and less frequently in southern Africa. Outbreaks are usually associated with periods of abnormally heavy rainfall or flooding. Between epidemics, the virus that causes Rift Valley Fever may remain dormant in eggs of mosquitoes. Cycling of the virus between mosquitoes and wild or domestic mammals has been shown to occur in many areas. VWhen emergence of infected mosquitoes, or introduction of virus to an area, coincides with abnormally wet conditions and the presence of a highly susceptible host population, a large epidemic may ensue when the virus is amplified in mammals and spread locally by many species of mosquitoes. The incidence of RVF peaks during the late rainy season. In areas with cold winters, both the disease disappears after the…

Unlike  some positive  (+) strand  RNA viruses,  what must all negative (-)  strand RNA  viruses  package  within  virions  in  order  to o make mRNA upon infection  of new host cells?

If you extract the DNA of the coliphage φ X174, you willfind that its composition is 25 percent A, 33 percent T,24 percent G, and 18 percent C. Does this compositionmake sense in regard to Chargaff’s rules? How wouldyou interpret this result? How might such a phage replicate its DNA
