Top 20+ Best Free Online Courses for Biology Today

Online learning is the current trend of education, actually it has been around for a long time, but it is not used much. Due to the Covid-19 pandemic, it has to be used as it is the safest way to still deliver quality education and schools that don't use it have to start doing it.

Online learning has a host of advantages it offers to learners, and you still get the same kind of education even when you're sitting in a classroom.

Online learning is flexible, fast to complete, cheap - free in some cases - and almost anyone can join no matter where in the world you are. You just need Wi-Fi and a computer/tablet.

With e-learning, individuals with a background in biology can learn completely online and in this case for free.

Without further ado, we recommend taking free online biology courses to kick-start your career in this field.


1. Introduction to Biology – The Secret of Life


Professor Eric Lander, one of the Human Genome Project's leaders, teaches 7.00x, a basic biology course.

The topics covered in the course are similar to those taught in MIT's introductory biology courses and many other biology courses around the world.

As a student, you will first focus on the structure and function of macromolecules such as DNA, RNA, and proteins.

You'll also learn how structural changes in certain macromolecules affect their functions and how these changes affect human health.

You'll learn how to apply your knowledge of genetics and cell information flow to human health and disease, as well as molecular biological tools and their potential to impact our changing world as you progress through the course.

You will have a solid understanding of biology after completing this course, which will allow you to comprehend the current medical revolution.

MITx 7.00x Introduction to Biology The Secret of Life delves into biochemistry, genetics, molecular biology, recombinant DNA technology and genomics, and rational medicine.
