This self-paced course was originally designed to help prepare incoming MIT students for their first Introductory Biology Course (known at MIT as 7.01). It will also be useful for anyone preparing to take an equivalent college-level introductory biology class elsewhere. It includes lecture videos, interactive exercises, problem sets, and one exam. Lecture Topics: Molecules of Life, The Cell and How it Works, Information Transfer in Biology, Inheritance and Genetics, and Building with DNA. Go to OCW’s Open Learning Library site for Pre-7.01: Getting up to Speed in Biology. The site is free to use, just like all OCW sites. You have the option to sign up and enroll in the course if you want to track your progress, or you can view and use all the materials without enrolling.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"A fundamental law of genetics states that offspring do not inherit traits from their parents that were acquired in response to environmental conditions. Recent research in the field of epigenetics, however, is turning this principle on its head. Several recent studies have come to the remarkable conclusion that unhealthy diets in males can contribute to the development of metabolic diseases in their offspring. Even when those offspring are raised with healthy diets_._ Now, a study has identified small RNAs as the molecules responsible for the transmission of these disorders. For a long time scientists thought that inheritance of traits only occurred via DNA being passed from parent to offspring. It is now clear, however, that the experiences of one generation can have an effect on the next. When parents have a high-stress lifestyle or an unhealthy diet, for example, chemical modifications can occur on genes that are then passed to their children. This is termed ‘epigenetic inheritance..."
