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

Learn about transcription using this visual graphic and detailed list of the various steps that take place during the process.

Read about the three-phase process of protein synthesis. This resource includes helpful diagrams and detailed information about initiation, 3 steps of elongation, and termination.

Provides some very straight forward information regarding genetic information an DNA. Find out about synthesizing proteins, the Central Dogma of molecular biology, and much more.

Microscopic images, detailed information, and illustrated diagrams help explain DNA and molecular genetics in this college-level textbook.

Explains what homologous structures are and how they indicate common ancestry between species. Discusses morphological homology, which refers to anatomical and skeletal similarities, and molecular homology, which refers to common...

The homeobox genes that define the basic body plan of mice and fruit flies are illustrated in this graphic from The Human Evolution Coloring Book by Adrienne Zihlman. The accompanying article describes how these genes act as "molecular...

The Northern blot and the Southern blot are two methods used to analyze DNA and RNA. Each technique is described, its purpose, and the methodology. A table comparing features of each is provided.

College-level biotechnology course highlighting a science basis for bioengineering focusing on molecular cell biology and systems biology. Course contents include video lectures and interviews of bioengineering faculty, lecture notes,...

These pages are part of a site called Evolution that accompany a textbook by the same name. Mark Ridley is the author. In this section: the universal genetic code provides evidence that life has a common ancestor.

This cellular biology page presents extensive detail on the chemical nature of the cell membrane. Using the Chime plug-in, students can manipulate and study models of the membrane.

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...

An interactive, self-paced lesson on polymerase chain reaction. Students read information and watch descriptive animations to aid in understanding. A self-check quiz follows the activity.

With developments in molecular biology, biologists have powerful new tools to determine the relatedness of specimens found at different locations. Studies of chromosomes and gene sequences have helped identify Cockrum's Gray Shrew and...

Good information about various milestones in genetics history. Check out the links on the bottom of the page for additional information.

Biology Project tutorial from the University of Alabama explains the molecular events that occur as a pigment molecule absorbs a photon of light during photosynthesis.

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

Article explores the life cycle of a cell and delves into the phases of the cell cycle.

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

Learn how cells use checkpoints to regulate the cell cycle. This article provides an overview of cell cycle control, outlining the factors that influence a cell's decision to pause or progress at each checkpoint.

This article looks at a few of the most important core cell cycle regulators: proteins called cyclins, enzymes called Cdks, and an enzyme complex called the APC/C.
