Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

In this class, students engage in independent research projects to probe various aspects of the physiology of the bacterium Pseudomonas aeruginosa PA14, an opportunistic pathogen isolated from the lungs of cystic fibrosis patients. Students use molecular genetics to examine survival in stationary phase, antibiotic resistance, phase variation, toxin production, and secondary metabolite production. Projects aim to discover the molecular basis for these processes using both classical and cutting-edge techniques. These include plasmid manipulation, genetic complementation, mutagenesis, PCR, DNA sequencing, enzyme assays, and gene expression studies. Instruction and practice in written and oral communication are also emphasized.

Fundamentals of Biology focuses on the basic principles of biochemistry, molecular biology, genetics, and recombinant DNA. These principles are necessary to understanding the basic mechanisms of life and anchor the biological knowledge that is required to understand many of the challenges in everyday life, from human health and disease to loss of biodiversity and environmental quality. Course Format
This course has been designed for independent study. It consists of four units, one for each topic. The units can be used individually or in combination. The materials for each unit include:
Lecture Videos by MIT faculty. Learning activities, including Interactive Concept Quizzes, designed to reinforce main concepts from lectures. Problem Sets you do on your own and check your answers against the Solutions when you’re done. Problem Solving Video help sessions taught by experienced MIT Teaching Assistants. Lists of important Terms and Definitions. Suggested Topics and Links for further study. Exams with Solution Keys.

"The next time you swat away that fly buzzing around your head, consider this: an international team of researchers has shown that common houseflies and blowflies are more than just annoying insects. Covered with hundreds of different bacterial species, they’re also a type of airborne delivery service, transporting pathogens from organic decaying matter right to your countertops, food…and body. Although flies have been long known to spread disease, the researchers show that we’ve previously underestimated both the number and diversity of microbes that each insect can transmit. The team devised a new optimized way to collect flies without cross-contaminating them with other microorganisms and used the method to amass 116 flies from urban, rural, and natural sites on three continents..."

"Roaming the forest floor, these army ants are doing what army ants do best: hunting insects to bring back to the colony. But they're not alone. The practice of gathering and consolidating enormous amounts of food has piqued the interest of other insects looking for an easy meal. It's a scene that plays out in most army ant communities; rarely are these colonies composed exclusively of ants, but often include numerous 'guest' species. A team of researchers from the US and Germany recently conducted a survey of these _guests_ in the tropical rainforest of Costa Rica. Using their morphological expertise and DNA sequence data, they were able to identify several new species of insects that had integrated themselves into the ant colonies. Among them, a hitch-hiking beetle disguised as an ant’s rear-end. Unlike most ants, army ants are nomadic. During their most active periods, the colony will move to a new nest site every day. This presents two difficult tasks for guest insects..."
