Understanding the Human Genome

The video discusses the human genome, highlighting its complexity beyond just genes, and the Human Genome Project's role in uncovering surprises about gene count and non-coding DNA. It explains how the project has transformed genetic research, leading to discoveries about viral DNA and evolutionary remnants in our genome. The video concludes by encouraging further exploration of genetics through SciShow.

What are the four chemical bases that make up DNA?
