You are interested in understanding the regulation of nuclear lamina assembly. To create an in vitro system for studying this process you start with partly purified nuclear lamina subunits to which you will add back purified cellular components to drive nuclear lamina assembly. Before you start doing experiments, your instructor suggests that you consider what type of conditions would be most amenable to the assembly of the nuclear lamina from its individual subunits in vitro. Which of the following additions do you predict would be most likely to enhance the assembly of the nuclear lamina?

a. addition of phosphatase inhibitors
b. addition of ATP
c. addition of a concentrated salt solution that is 10 times the concentration normally found in the nucleoplasm
d. addition of protein kinase inhibitors

A 28 year old woman, 18 weeks pregnant following a one-night stand unprotected sexual encounter, went to her doctor after 36 hours of headache, fever, nausea, and vomiting. Her doctor admitted her to the hospital immediately with a 104F fever and neck stiffness. All neurological exams were otherwise normal. A gram smear of the CSF (test 1) was conducted and revealed gram-negative diplococci and culture on chocolate agar showed small colorless colonies (test 2). The doctors treated her with an antibiotic, but also performed a third test to confirm diagnosis molecularly. She recovered without any complications,

When H. pylori was first discovered, researchers doubted the finding. It was thought that the acidic environment of the stomach was too hostile for microbes to thrive. Newer research using genetic analysis and culture techniques has revealed that there is a diverse gastric microbiota. Of the options below, what is the only one that does not involve genetic analyses?
A. Sequencing approaches have shown that the normal microbiota includes Archaea and provide mechanisms for studying their distribution.
B. Knowledge of growth rates allows researchers to predict responses to changing conditions.
C. Knowledge of the microbiota from sequencing efforts has been used to improve cultivation techniques.
D. Genetic analyses have been used to examine the dominant species in different individuals, showing that it varies from one individual to another.
