Fundamentals of Biology
Course Description
Why are some diseases genetic? How do cells divide? What is DNA, and how does it work? This course gives you the answers. MIT's Fundamentals of Biology is a comprehensive introduction to the core principles of life itself.
You'll explore the basic mechanisms of biochemistry, molecular biology, genetics, and recombinant DNA. These aren't just academic topics—they're the keys to understanding human health, disease, biodiversity, and environmental quality. The course is designed for independent study and works for high school students, college students, or anyone who wants a rigorous, university-level biology foundation.
This completely free, self-paced course includes over 20 hours of video lectures by renowned MIT faculty (including Eric Lander, Robert Weinberg, and Tyler Jacks), interactive concept quizzes, problem sets with solutions, problem-solving video sessions, and exams with answer keys. There's no enrollment or deadline. Just start learning.
Course Provider
Provider: MIT OpenCourseWare (OCW), a web-based publication of virtually all MIT course content. OCW is free and open to the world.
Platform: MIT OCW website – no login required. All materials are downloadable.
Faculty: This course was developed by an all-star team of MIT biologists, including Eric Lander (founding director of the Broad Institute), Robert Weinberg (Whitehead Institute), Tyler Jacks (former director of the Koch Institute), and others.
Accreditation: OCW does not offer certificates or degrees. You take the course for your own learning. However, the knowledge is equivalent to an introductory MIT biology course.
Course Syllabus (4 Units)
Each unit includes lecture videos, interactive concept quizzes, problem sets, problem-solving video sessions, a list of key terms, and a final exam with solutions.
Learning Objectives
- Understand the basic chemical principles that govern life: biochemistry of proteins, enzymes, and nucleic acids.
- Explain the central dogma of molecular biology: how DNA is replicated, transcribed into RNA, and translated into proteins.
- Apply Mendelian genetics to predict inheritance patterns and understand genetic variation.
- Describe the tools of recombinant DNA technology, including PCR, cloning, and DNA sequencing.
- Connect biological principles to real-world challenges: genetic disease, cancer, biodiversity loss, and biotechnology.
- Develop problem-solving skills through MIT-style problem sets and exams.
- Build a foundation for further study in biology, medicine, or environmental science.
Course Prerequisites
Academic: High school-level biology and chemistry are helpful but not strictly required. The course starts from first principles. A willingness to learn and a comfort with basic scientific concepts is sufficient.
Math: No advanced math required. Basic algebra is useful for genetics problems.
Language: The course is taught in English. Lecture videos include transcripts.
User Reviews
"This is the gold standard for free biology education. The professors are world-class, the materials are complete, and the problem sets are challenging but fair. I used this course to prepare for my college biology placement test and placed into advanced courses. Thank you MIT!"
"As a self-taught programmer who wanted to shift into bioinformatics, I needed a solid biology foundation. This course gave me exactly that. The recombinant DNA unit was particularly valuable. The fact that it's free and from MIT is incredible."
"Excellent content, but be prepared to work. This is a real MIT course, not a watered-down 'intro for non-majors.' The problem sets are tough, and the pace is fast. But if you put in the hours, you'll learn more than in many paid courses. The interactive concept quizzes are very helpful."

If you want to understand the science of life—whether for academic credit, career change, or pure curiosity—this is the course to take. Just remember: you don't get a certificate, but you get something better: genuine, MIT-quality knowledge.
Fundamentals of Biology (MIT) – FAQ
Is this course really free?
Yes, completely free. MIT OpenCourseWare is an open educational resource. You don't need to register or pay anything. All materials are freely available online.
Do I get a certificate?
No, MIT OCW does not offer certificates or grades. You take the course for your own learning. However, many learners list OCW courses on their resumes or LinkedIn profiles under "Continuing Education."
Is this course for high school students?
Yes, motivated high school students can definitely succeed. The course is also appropriate for college students, self-learners, and anyone wanting a rigorous biology foundation.
Do I need to buy a textbook?
No. All required materials are provided online, including lecture notes, problem sets, and exam solutions. You can use a standard biology textbook if you want additional reference, but it's not required.
How is this different from a MOOC?
This is a self-study course, not a structured MOOC. There are no deadlines, instructors, or peer interaction. You work through the materials at your own pace, entirely independently. For many learners, this flexibility is a benefit.
What if I get stuck on a problem?
The course includes problem-solving videos where MIT teaching assistants work through problems step by step. You can also find community discussions on the OCW website or external forums like Reddit's r/biology.
