Q1. Researchers tried to describe how vesicular transport occurs in cells by attempting to assemble the transport components. They set up microtubular tracks along that vesicles could be transported, and they added vesicles and ATP (because they knew transport process requires energy). Yet, when they put everything together, there was no movement or transport of vesicles. What were they missing?
Q2. Type S Streptococcus pneumoniae bacterium is lethal and will kill its host. If heat inactivated S strain becomes nonlethal. Type R Streptococcous pneumoniae is a nonvirulent strain of bacteria. What would happen if one were to inject both the R strain and heat-killed S strains into a host organism such as the mouse?
