О курсе

Read fully to understand the verified-certificate option. Join Professor Eric Lander and the MITx Biology team in this unique introductory biology learning experience. All 7.00x course materials are available here for exploration and completion, including video and interactive problem sets and exams for skill building. We strongly encourage you to work through the activities, towards a goal of learning biology. We have optimized the course settings for learning: instant feedback after trying problems and all content available at all times. We offer a rigorous means of certifying edX learners in their mastery of the MITx introductory biology content, through the MITx 7.00x Introduction to Biology Competency Exam. This exciting option is available ONLY to those who register for the verified-certificate track, and successful completion of this exam is the only assessment that counts toward a certificate. We highly recommend preparing for the Competency Exam certification by using the current course materials and MIT OpenCourseWare problems. The next Competency Exam will be open February 20, 2018 to February 27, 2018.

7.00x is an introductory level biology course hosted by professor Eric Lander, who was one of the leaders of the Human Genome Project. The course content reflects the topics taught in the MIT introductory biology courses and many biology courses across the world. As a learner, you will first focus on the structure and function of macromolecules such as DNA, RNA and proteins. You will discover how changes in the structure of some of these macromolecules alter their functions and what the implications of such changes have on human health. As you continue in the course, you will apply an understanding of heredity and information flow within cells to human health and disease and will learn about molecular biological techniques and their potential to impact our changing world. After you complete this course, you will have a foundation in biology that will allow you to understand the remarkable medical revolution going on today.

MITx 7.00x: Introduction to Biology – The Secret of Life will let you explore the mysteries of biochemistry, genetics, molecular biology, recombinant DNA technology and genomics, and rational medicine. We are excited to take this journey with you!
