Your lazy labmate needs your help! They set up a 10-ml culture of the slow-growing Myxococcus
xanthus yesterday, but then they decided to stay up late playing videogames and won't be in until
next Monday to recover. Whoops! They call you in lab that Friday and ask you to take an OD
reading for them. You do this favor for them, and helpfully do the conversion into cells/mL,
finding that their culture is currently sitting at about 3.0 x108 cells per mL. Your labmate is
horrified: they won't be back in time before the cells hit stationary phase, since M. xanthus
doubles every 5 hours. They beg you to make a new culture using these cells and set it up to
reach the same cell density Monday morning. That's 59 hours away. If the cells usually lag for
three hours upon dilution into fresh medium, what cell density should you dilute the culture to?
About 1.3 x 107 cells/ml
About 1.3 x 105 cells/ml
About 1.3 x 106 cells/ml
About 1.3 x 104 cells/ml
Interpret these images and identify the unkown bacteria

Therefore, dependent on the surface properties, nanomaterials efficiently adsorb biomolecules and form a so-called biomolecular corona. This passive, nontargeted adsorption might be utilized to bind viruses, provided that the selected nanomaterial is relatively biocompatible. Viral surface proteins are often modified by sugar moieties or encompass positively charged amino acid patches that bind to lectins or glycosaminoglycans (GAGs) of heparan sulfate…arrow_forward
- TRY TO KEEP IN SHORT AND USE OWN WORD FOR THIS QUESTION You are studying a type of bacteria isolated from the acidic water runoff of a mining operation. You subject two batches of the same bacteria type to different environmental growth conditions. One batch is grown at pH 2, while the other is grown at pH 7. All other environmental parameters are kept identical between the two batches. You then collect their proteins and run a Western blot using an antibody that binds to a proton efflux pump protein (which actively expends energy to pump protons out of a cell). How would you characterize the information obtained in this experiment? What does it tell you, and why is that potentially valuable information?arrow_forwardWhat makes platinum replica EM more desirable than conventional SEM and TEM (address both, specifically) for imaging cytoskeleton?arrow_forwardplease help summary Results Labeling HIV-1 Capsids with a GFP Fluid Phase Marker. To determine whether viral cores in infected cells retained their integrity, we utilized a previously described HIV-1 vector in which GFP was inserted between matrix (MA) and CA (pNL4-3 Gag-iGFP) (35) (Fig. 1A). Proteolytic processing during virion maturation releases GFP from the Gag precursor, some of which remains trapped inside the capsid and is released upon loss of core integrity (Fig. 1B). We also utilized a previously described RNA stem-loop system in which 18 copies of BglG stem loops (BglSLs) were engineered into the HIV-1 genome in place of vif/vpr to facilitate the detection of nascent HIV-1 genomic RNA at the HIV-1 transcription site (Fig. 1A). This system can be used to identify the capsids that lead to productive infection and determine the nuclear location of integration (25). Virions were produced by cotransfection of an HIV-1 vector expressing Gag-iGFP and a vector expressing wild-type…arrow_forward
