About This Course
If you need to review cell and molecular biology topics, look no further than Biology 203. Consisting of short video lessons, this course explains the basics of cell and molecular biology through simple definitions and illustrative examples. Work through the course at your own pace to study biological molecules, cell functions, cellular transport, photosynthesis, DNA replication, cell cycles, genetic inheritance, viruses and more.
Use this course to get ahead in a science class, study for an exam or simply learn more about these biological concepts for fun. The course comes with lesson quizzes and chapter exams to help you retain key terms. You can access the course any time that fits your schedule, and your course dashboard will keep track of our progress. You'll also be able to submit any questions you may have through the course's Ask the Expert feature.
