The Molecular Biology Web Book You can read this book online for free or download an electronic version which you will be able to open 3 times before having to insert a key (sold on the website).
A Biology Hypertextbook Presented items are modified lecture outlines the author have developed over the many years of teaching college-level introductory biology.
Excellent for students and education purposes. Rich in nice images collected over the years.
A Molecular Biology Notebook Educational and research resource for students and biologists. Simple and clear tutorials on the cell, the DNA, Molecular Engineering and much more.
BioDidac A bank of digital resources for teaching biology. Great educational site.
Biology in Motion Here you will find animations, interactive activities, and cartoons designed to make learning biology a rich and engaging process.
Biology Student Workbench The goal of Biology Student Workbench is to promote the use of molecular data in the identification and exploration of biological problems with an evolutionary perspective throughout undergraduate biology curricula. This will be accomplished by providing undergraduate faculty and students access to the powerful state-of-the-art bioinformatics tools currently in use by the research community transformed to afford a cognitively supportive environment. These products will enable undergraduate students to investigate current problems in biology using molecular biology tools and skills.
The Biology Project An online interactive resource for learning Biology from the University of Arizona. Very well done! Main sections: Biochemistry-Cell Biology-Chemicals and human health-Developmental Biology-Human Biology-Immunology-Mendelian Genetics-Molecular Biology
The Home page of Ruediger Rudolf "This site contains micrographs, short videos, species descriptions, and detailed information on several groups of the aquatic animal life. Two of these - the cladocerans (e.g., Daphnia, Podon) and the rotiferans (e.g., Rotifer, Synchaeta) - undergo a special life cycle, alternating between sexual and asexual reproduction, the so called heterogony. As such, some extra information on this aspect of biology is also provided.
The Molecules of Life A school-level interactive resource by Craig D. Livingstone and Martin E. Noble, with photographs, schemes and even movies illustrating clearly and shortly the main techniques used in a biophisics-biochemistry lab "to gain understanding on the structure of protein molecules.
