Khan Academy: Applications of Dna Technologies

Introduction to DNA cloning. [11:07]

Learn about the experiments by Frederick Griffith, Oswald Avery, Alfred Hershey, and Martha Chase that led to the discovery of DNA as the genetic material.

See a key historical experiment that demonstrated the semi-conservative mechanism of DNA replication.

Learn about DNA (deoxyribonucleic acid), overview of DNA bases, complementary base pairing, and the structure of the double helix. [13:01]

We solve the equations created by direct application of the fundamental laws: Ohm's Law and Kirchhoff's Laws. (Part 2 of 2) [8:40]

We can solve circuits by the direct application of the fundamental laws: Ohm's Law and Kirchhoff's Laws. (Part 1 of 2) [8:01]

We solve a circuit by direct application of the fundamental laws: Apply element laws (Ohm's Law and the like) plus Kirchhoff's Laws to solve for the currents and voltages of a circuit.

A video discussing the molecular structure of DNA. Understand that DNA is made up of a phosphate, deoxyribose sugar, and one of the four nitrogen base. Video also explains how the nitrogen bases pair up to form the double helix...

Explore the molecular structure of DNA in this article. Learn about the components of DNA: nucleotide, nitrogenous base, and phosphate.

Learn the basics of the structure of DNA strands in this video. [9:56]
