Answer #1

Answer: A . They would have concluded that protein from virus entered bacteria. In the experiment they radiolabelled phage DNA with P32 or coat protein with S35. Virus has a protein coat which surrounds a DNA molecule. They labelled protein and DNA one at a time. Thus one single virus population consisted of P32 labelled DNA and other consisted of  S35 labelled protein coat. These two different radiolabelled virus populations were allowed to attach to bacteria for a while before disrupting their association by blending. Next centrifugation was done to separate the virus from bacteria. Bacteria came in pellet and virus came in supernatant. If the pellet contained radioactive sulphur that means that protein from virus has entered bacteria because pellet contains only bacteria.

In the Hershey/Chase experiment phage proteins and DNA were radioactively labeled and allowed to inject coding material into bacteria. It was found that only radioactively labeled DNA was present in the bacterial cells which had been transformed. If radioactively labeled protein had been discovered in the transformed cells, what would this have told us about the molecules acting in genetics?

The movements of newly synthesized proteins can be followed through cells using a "pulse-chase" experiment.  During synthesis, proteins are tagged with a radioactive isotope (the "pulse"), then the cells are allowed to process the proteins for varying periods of time.  The locations of the radioactive proteins are then determined by isolating cell organelles and quantifying their levels of radioactivity. What would be the expected pathway for a protein that is secreted from the cell?

In the experiment, Okazaki cultured E. coli (at low temperatues to slow down replication process) in the presence of radioactive nucleotides. They did this for short pulses followed by the addition of excess nonradioactive nucleotides. This resulted in label (radioactivity) being present only in the DNA that was synthesized during the short period of the pulse. Soon after the pulse, they isolated the DNA and separated the individual strands from one another. The various pieces of DNA could then be...

Most organisms carry their hereditary genetic information as DNA. However, some viruses use RNA instead. The HIV virus has RNA, but its genetic information is found in host DNA. How does this happen? a. An enzyme reverses the usual process, producing DNA from the viral RNA. b. The viral RNA goes through translation in the host cell. c. The viral RNA is actually a variant of DNA. d. Viral RNA attaches to the host’s chromosomes.

1) In most laboratory applications, for plate counts to be considered valid, they must have between 30 and 300 colony forming units on them. To achieve this, scientists must dilute the sample prior to plating it. If a culture of bacteria is experiencing exponential growth has 8,449 cells per mL, and an instantaneous growth rate constant of 0.5 hours-1, after 2 hours, what is the total dilution that needs to be performed to yield 71 colony forming units on an...
