Interphase of the cell cycle, including G₁, S, and G₂ phases. How the cell replicates its DNA before mitosis.
Microsoft founder Bill Gates gives a quick overview of the entire How Computers Work series.
In this video we discuss some of the key parts of Bit-zee. Created by Karl Wendt.
Brief overview of what we'll cover in this lesson.
Amino acids and the central dogma of molecular biology. Amino and carboxyl groups, side chains, and zwitterions.
Introduction to carbohydrates (saccharides). Monomers and polymers. Glucose and glycogen.
Introduction to centripetal force, which accelerates an object toward the center of the circular path.
Introduction to Channel Capacity & Message Space. Created by Brit Cruise.
Welcome to our lesson on character development.
Introduction to cilia, flagella and pseudopodia.
Ohm’s Law is V = IR, where V = voltage, I = current, and R = resistance. Ohm’s Law allows you to determine characteristics of a circuit, such as how much current is flowing through it, if you know the voltage of the battery in the circuit and how much resistance is in the circuit.

Kinetics is the study of reaction rates and how they are affected. Many factors, such as concentration, pressure, temperature, and enzyme activity, can impact the rate of a reaction. For example, a molecule's kinetic energy is directly proportional to its temperature, so increasing the temperature will result in an increase in reaction rate. Created by Sal Khan.
