This video lesson is designed for Class 12 Biology (India). This video lesson explains how new discoveries have expanded or contradicted the original central dogma of molecular biology as proposed by Watson and Crick. These discoveries...

Constructing phylogenetic trees may be a daunting task for students, but this lesson plan is a simulation of what molecular biologists must do to determine relationships. This plan is for students who have a good grasp of DNA structure...

This lesson focuses on the molecular biology technique of DNA fingerprinting: what it is, how it works, and how the data from these experiments are used for paternity testing and forensics. [45:48]

In this video segment adapted from NOVA: "Judgment Day: Intelligent Design on Trial," students will learn how modern genetics and molecular biology offer compelling support for evolution. The video features an interview with biologist...

This is a great lesson plan that combines Karoytypes and evolution. Students will recognize that the chromosomes of chimpanzees and humans are remarkably similar, then correlate that to their evolutionary relationship.

Learn the molecular structure of RNA. [11:29]

Discover the molecular structure of DNA: nucleotide, nitrogenous base, and phosphate. [13:00]

View this video that contains 3 minutes of amazing cel animation created by David Bolinsky. In the video he discusses the project that was designed for the Molecular and Cellular Biology Department at Harvard. Included is a complete...

This lesson plan focuses on differences in the amino acid sequence of hemoglobin and myoglobin proteins. They use the number of differences to create a phylogenetic tree.

A video discussing how three fatty acids and a glycerol molecule come together to form a triglyceride. [11:03]

Learn the basics about the forces between molecules called intermolecular forces in this video. [8:35]

Watch how NJ high school students apply basic principles of molecular biology to solve real research probloms and publish their own genome research at GenBank, the international genomic sequence database. [6:12]

Paul Andersen describes the structure and explains the properties of molecular solids. High intramolecular forces hold electrons and reduce conductivity, whereas low intermolecular forces decrease the melting point. Important polymers...

Paleontologists and molecular biologists have searched for a couple of decades to find and replicate DNA from some non-avian dinosaur fossil. [0:59]

[Free Registration/Login may be required to access all resource tools.] A dynamic, 3-D, computer-animated video that takes you inside for a close-up look at how humans are made. Watch as the mysteries of the human genome are literally...

Introduction to DNA cloning. [11:07]

Introduction to gel electrophoresis and how it's used to separate DNA fragments or other macromolecules. [10:59]

Introduction to PCR (polymerase chain reaction). [9:53]

Introduction to genetic engineering, human breeding, recombinant DNA, and bioethics. [6:31]

Use an amino acid translation table to understand the impact of point and frameshift mutations. [8:52]

Learn how DNA is copied (replication) and how information in DNA can be used to make a protein. [15:23]

Understand the roles of DNA polymerase, primase, ligase, helicase and topoisomerase in DNA replication. An explanation of leading and lagging strands. [10:18]

Understand how DNA is composed of two strands of nucleotides held together by hydrogen bonding and see the strands each run in antiparallel directions from one another. [9:56]

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