Phagehunter Lab Has Undergraduates Searching for Tuberculosis Cure
Field of bacteriophage plaques. A bacteriophage, or phage, is a virus that infects a bacterium and reproduces inside it killing the bacterium, then infecting those around it. Ultimately such infections spread to give clear areas in a lawn of bacteria
Packaging Process for Genes Discovered in New Research
Like a strand of white pearls, DNA wraps around an assembly of special proteins called histones (colored) to form the nucleosome, a structure responsible for regulating genes and condensing DNA strands to fit into the cell's nucleus. Credit: Karolin Luger
