How do inducible promoters work? Promoters control the binding of RNA polymerase and transcription factors. Since the promoter region drives transcription of a target gene, it therefore determines the timing of gene expression and largely defines the amount of recombinant protein that will be produced. What is a CMV promoter? What is a CMV promoter? […]

What prevents sperm from reaching the egg?
What prevents sperm from reaching the egg? Cervical mucus may prevent sperm from passing into the uterus, but during ovulation when the egg is released from the ovaries, the mucus gets thinner and lower in pH. These changes make the mucus a great transport medium for the sperm, and help the sperm continue traveling. What […]
What is the focal length of a spherical mirror if the radius of curvature is 30 cm?
What is the main purpose of transformer?
What is the main purpose of transformer? 1) What is a transformer and how does it work? A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to “step up” or “step down” voltages and works on the magnetic induction principle. Which part of transformer […]
What are the two major types of somatoform disorders?
What are the two major types of somatoform disorders? The two main types of somatoform disorders that produce psychogenic neurologic problems are conversion disorder and somatization disorder; the latter is also known as hysteria or as Briquet syndrome. Other somatoform subsets are hypochondriasis, somatoform pain disorder, and body dysmorphic disorder. Do I have a somatoform […]
What is the trend of a line?
What is the trend of a line? A trendline is a line drawn over pivot highs or under pivot lows to show the prevailing direction of price. Trendlines are a visual representation of support and resistance in any time frame. They show direction and speed of price, and also describe patterns during periods of price […]
Can a magnetic field do work on a moving charged particle?
Can a magnetic field do work on a moving charged particle? The magnetic force does no work on a charged particle. Therefore a magnetic field cannot be used to increase the energy of a charged particle. If v and B are perpendicular the particle will move in a circular path. Why do magnetic fields only […]

What is enthalpy vs free energy?
What is enthalpy vs free energy? Enthalpy and Gibbs Free Energy indicate different things. Enthalpy can tell you about the relative stabilities of the products and reactants. Gibbs free energy however can tell you about whether a reaction is spontaneous (whether a reaction will occur) under a set of specified conditions. How is entropy related […]
