How can a plasmid be inserted into a bacterial cell? How can transformed bacteria carrying a recombinant plasmid be distinguished from untransformed counterparts? These questions and more will be answered in this lesson. Genetic Engineering and Bacterial Transformation We have been discussing one method of creating human insulin for diabetic patients. To this point, our […]
Rational functions are an extremely useful type of function found in mathematics. They are functions that are fractions whose numerator and denominator are both polynomials. Learn all about them in this lesson! Definition of a Rational Function A rational function is a function that is a fraction and has the property that both its numerator […]
Watch this video lesson to learn how you can estimate problems with decimals in them so you can get a quick answer when you need it – for example, when you are at the gas station and you need to know how much gas you can afford. A Word Problem This video lesson is about […]
Learn what editing for content means and how it’s different from editing for spelling, punctuation and grammar. Review the list of things to look for in a content edit. Read the lesson, and then take the quiz to test your new knowledge. Editing for Content After you’ve finished writing your essay, you already know that […]
In this lesson, we’ll conduct a brief review of enzymes, including what they are and what they do. We’ll also use the analogy of a light switch to explore allosteric regulation and the reason that the process is so important to enzymes. Overview of Enzymes Have you ever wondered what happens to a hamburger once […]
Given a particular function, there is actually a 2-step procedure we can use to find the horizontal asymptote. Learn what that is in this lesson along with the rules that horizontal asymptotes follow. Definitions Before getting into the definition of a horizontal asymptote, let’s first go over what a function is. A function is an […]
In this lesson, you’ll learn some ellipse terminology. You’ll also learn the formula for the area of an ellipse and go through a few examples of the equation in action. Then, you can test your new knowledge with a brief quiz. What Is an Ellipse? An ellipse is an oval that is symmetrical along its […]
The use of antibiotic selection and positive and negative controls are important elements of interpreting data from a bacterial transformation. In this lesson, you will learn how antibiotic selection results in colony formation and how controls help pinpoint the cause of experimental problems. Review of Bacterial Transformation and Genetic Engineering We have been considering the […]
If you can solve linear equations, you can solve linear inequalities. In this lesson, you will learn how similar the solving processes are. You will also learn the notations you need to use when graphing linear inequalities. What Is a Linear Inequality? A linear inequality is very similar to a linear equation. Recall that a […]
Do you ever hear things that aren’t really there, or not hear something that’s nearby? You’re not going crazy, this is common. In this lesson we are going to look at signal detection theory and explore how your mind detects or misses various signals. Signal Detection Have you ever done that thing where you could […]
