Description

This animation describes how only a small part of the human genome directly codes for proteins.

As shown in the animation, only 1% of the human genome is directly translated into the amino acid sequences that make up proteins. Of the rest, about 25% make up genes and their regulatory elements, such as promoters or enhancers. The functions of the remaining sections of the genome are still unclear.

Depending on students’ background, it may be helpful to pause the animation at various points to discuss different features.
