For each statement below, determine whether each condition will promote microtubule polymerization or depolymerization. The addition of a drug that caps the plus end of the microtubule and prevents subunit exchange at the plus end will promote microtubule [answer1]. The addition of a drug that prevents GDP-tubulin from dissociating from the polymer will promote microtubule [answer2]. The addition of a drug that inhibits GTP hydrolysis in subunits incorporated into the polymer will promote microtubule [answer3]. The addition of a drug that promotes GTP hydrolysis in the microtubule will promote microtubule [answer4].

Which of the statements below about intermediate filaments is true?

What are the key elements to successful closed-loop thinking in lean management?

Normally, when blood glucose level increases (e.g. after a meal), the islet cells in the pancreas secrete insulin. When insulin molecules bind to insulin receptors on the surface of a muscle cell, the receptors become activated, initiating a signaling pathway which eventually results in the increase in the number of passive glucose transporters on the muscle cell surface thus increases the uptake of glucose.  Which one of the following conditions will likely result in diabetes?

According to W. Edwards Deming, what is a key feature of organizational leadership?

Indicate whether the following statements are true or false.  [answer1] Reovirus enters into the target cell by first being captured as a “cargo” into a endocytic vesicle. [answer2] Reovirus is activated when an outer shell viral protein is attacked by an intestinal protease. [answer3] The nuclear envelop is thought to have evolved by invagination and pinching off from the plasma membrane of an ancient archaeon. [answer4] An antibiotic that inhibits protein synthesis of a bacterium will likely inhibit protein synthesis in mitochondria. [answer5] Most mitochondrial proteins are made within mitochondria.  [answer6] The electrical potential of a charged molecule is zero if the membrane potential is zero.

Which of the following statements regarding the nucleus is true?

A bacterium is suddenly dumped into warm culture media from a cooler environment. Which of the following adjustments will help the bacterium maintain the same level of membrane fluidity?

You have discovered a drug that blocks the ability of Ran to hydrolyze GTP.  When you apply this drug to a cell, what is the likely effect on nuclear import?
