What is the reason that closely linked genes are typically inherited together? - ANSWER The likelihood of a crossover event between these two genes is low All female mammals have one active X chromosome per cell instead of two. What causes this? - ANSWER Activation of the XIST gene on the X chromosome that will become the Barr body In his transformation experiments, what did Griffith observe? - ANSWER Mixing a heat-killing pathogenic strain of bacteria with a living nonpathogenic strain ca...

Decontamination - ANSWER Is the mechanical removal of most microbes from an animate or inanimate surface. Bacterial Endospores - ANSWER Bacterial endospores most resistant - usually require temperatures above boiling Vegetative Cells - ANSWER A cell that grows and divides under optimal conditions. Disinfection - ANSWER Destroys most microbial life, reducing contamination on inanimate surfaces- (not endospores) Sterilization - ANSWER Is the destruction of all microbial life. Antise...
