Discover the uses and production of monoclonal antibodies. Links to additional resources regarding these molecular antigens.

A collection of video lectures from an introduction to biology course taught at Massachusetts Institute of Technology. The course covers fundamental topics like biochemistry, genetics, molecular biology, and cell biology with thirty-four...

This page discusses how the cladistic level of classification includes information from molecular biology to establish evolutionary relationships. The page discusses how this information is used to do this.

This is an article describing the life and discoveries in molecular biology of Max Delbruck.

Through full-color images and concise information, learn about adenosine triphosphate, or ATP, the molecular unit of energy currency of cells.

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.

Online biology textbook discussing the chemical nature of water, and the importance of its molecular structure to life. Also discusses at length the organic molecules nucleic acids, proteins, lipids, and carbohydrates.

Interactive resource provides a problem set in which you will work with the types of genetic and biochemical information used to unravel the inner workings of the lac operator-repressor regulation system. Correct answers are reinforced...

Learn the roles of DNA polymerases and other replication enzymes. Understand the leading and lagging strands and Okazaki fragments.

Learn about the ELISA test in this learning module. Explore how the Enzyme Linked Immunosorbent Assay (ELISA) test can be used to see if certain antigens are present.

This lesson plan requires students to analyze DNA restriction maps to determine the differences in the sequence for several primates and humans. They then use the information to create a cladogram.

Learn how prokaryotes reproduce by binary fission, and find out the use of E. coli bacteria in molecular biology.

This is a lesson designed by a biology teacher. In it, students use maps and evidence of island age, molecular genetics, morphology, and distance apart to determine how the islands came to be occupied by different species of lizards. It...

Visualize the main driving force behind molecular biology, where DNA makes RNA, and RNA makes protein. [1:53]

Endocytosis enables cells to absorb extracellular nutrients that are needed for their survival. In receptor-mediated endocytosis, a protein receptor on the cell membrane binds to a nutrient molecule and facilitates its absorption through...

Explains the goals of the Human Genome Project. It also explains some of the ethical, legal and social challenges associated with this new technology.

Learn how molecular labels are used to direct proteins to different parts of the cell and to the cell exterior.

(This instructional activity is for a more advanced class such as honors or AP Biology.) The instructional activity will look at one of the most important tools to the molecular biologist, PCR (Polymerase Chain Reaction). The students...

Answer questions to practice for the MCAT on the topic of temperament.

This informative resource features an overview of genetic material: DNA, chromosomes, genomes, homologous chromosomes, sister chromatids, and haploid/diploid.

Tutorial examines how a cell divides to make two genetically identical cells and explores the four basic phases: prophase, metaphase, anaphase, and telophase.

Tutorial explains the steps of bacterial binary fission which is the process that bacteria use to carry out cell division.

In this tutorial students will learn how meiosis reduces chromosome number by half and become familiar with crossing over, meiosis I, meiosis II, and genetic variation.

Tutorial takes a look at the three types of sexual life cycles used by different organisms: diploid-dominant, haploid-dominant, and alternation of generations.
