Making Copies of an HIV Particle
Lesson
Students read an essay about HIV viral replication, learn the parts of a single HIV particle, and investigate the HIV replication cycle in a host cell.
Modeling an HIV Particle
Lesson
Students read an essay about the emergence of HIV/AIDS, then learn about the virus' basic structure by making three-dimensional paper models of an HIV particle.
X or Y: Does It Make a Difference?
Lesson
Students describe the functional differences of X and Y chromosomes, and explain the significance of these differences within the human genome.

A 3D Map of the Human Genome
Video
The human genome is two meters long but fits inside the microscopic nucleus of a cell. The genome also modulates the function of each cell so that the cells operate differently. What makes this happen? Suhas Rao and Miriam Huntley of the Aiden Lab describe a 3D map of the human genome at kilobase resolution, revealing the principles of chromatin looping.
How Does DNA Fold? The Loop Extrusion Model
Video
The human genome is two meters long, but it fits inside the microscopic nucleus of a cell. How is this possible? Research conducted in the Aiden Lab at Baylor College of Medicine suggests that the genome achieves this feat by forming loops and domains through a process called extrusion.
