List and describe the sequential steps of TRANSLATION in prokaryotic (bacterial) cells. Don’t be too detailed, but provide enough information about the key steps.
Antibiotic treatment can kill healthy colonizing bacteria leaving the treated patient susceptible to bacterial infection at that site. Name an infection commonly associate with antibiotic use. If you could develop a disk diffusion assay that could represent a replacement infection at a site of health bacteria clearance, draw what that zone of inhibition would look like.

Two distinct heat shock factors, called HSF1 and HSF2, recognize the same binding site in DNA. The figure shows the result of an experiment in which the effect of an anti-inflammatory drug, indomethacin, was studied. HeLa cells were cultured at 37°C (lane 1 [C, control] and lanes 3-10), or 42° C (lane 2; HS, heat-shocked). The cultures for samples 3- 10 were treated with various concentrations of indomethacin, indicated at the top of each lane. After treatment, nuclear protein extracts were prepared and mixed with 32P-labeled, double- stranded oligonucleotides containing the HSF binding site. Anti-HSF1 (samples 7 and 8) or anti- HSF2 (samples 9 and 10) antibodies were also added to some of the samples. The samples were subjected to electrophoresis in a nondenaturing polyacrylamide gel, and autoradiography was performed.arrow_forward
