- Katelyn had been working for Dr. Johnson for a month, and while she had become quite good at measuring inhibitionzones, she didn’t know why she was doing all this work. She had gotten very curious after she began doing all themeasurements on a new set of antibiotics. # is experiment involved infecting mice with MRSA and tracking how theMRSA grew over time.Data were collected by counting the cells of MRSA taken from $ uid samples from the mice. # e cells were measuredby taking one gram of the $ uid and spreading it over plates, but now Katelyn counted the colonies that grew on theplate after 24 hours. Because there were so many, she actually measured the colonies as “log CFU/g.” A CFU is acolony forming unit, or essentially a cell that will divide into a colony that can be seen. Because there can be so many,Katelyn measured them on a logarithmic (log) scale. # e raw data in her lab notebook looked like the following:Table 1.

The attack of a host cell is necessary for the virus to survive for all of the reasons listed EXCEPT one. That is they cannot synthesize proteins becayse they lack ribosomes and must use the ribosomes of their host cells to translate viral messenger RNA into new Eliminate proteins. A) they cannot produce or store energy in the form of ATP and have to get their energy from the host cell. B) they parasitize the host cell for basic molecules like amino acids, nucleotides, and lipids. D) they lack DNA/RNA so they must use the DNA of the host cell.
