Question
Chapter 30.3, Problem 1EQ
Summary Introduction
To describe: The reason why the investigators feed experimental mice germ-free food.
Introduction: An investigation is done by Blanton, Gorden, and Associates on mice. They did this investigation to prove the hypothesis which states that, if the microbiome is taken from a malnourished child is transplanted into the mice then this will affect the growth of the mice.

Is Sam’s suggestion for this modification to the procedure utilized in interrupted mating experiments valid? Explain. b) Much to the dismay of the researcher with whom Sam is working, Sam is not only forgetful, but he is also lazy! Rather than devoting the necessary hours to conducting his assigned interrupted mating experiments, Sam has decided that his time would be better spent modifying the F plasmid so that the experiments wouldn’t require quite so much time. The diagram below shows a map of the E. coli F plasmid, similar to that shown in lecture. Sam is determined to “get rid of some of the excess DNA” present in the plasmid. Please keep in mind that the PI in the lab in which Sam works utilizes these F plasmids for interrupted mating experiments between Hfr and F- cells as well as for interrupted mating experiments involving F+…arrow_forwardWhich example would benefit most from the use of pluripotent stem cells made from the patient's own cells?
