Bacteriophage phi29, computer model. Cross section of phi29 created using UCSF Chimera software and data from cryo-electron microscopy. Bacteriophages are viruses that infect bacteria. Phi29 infects Bacillus subtilis. This image shows the empty protein shell, known as the capsid, which normally encases the DNA. At the base are proteins that form the 'tail' and a 'portal' (light green, red). The portal is a molecular motor that powers the packaging of DNA within the virus and injection into a host. Cryo-electron microscopy uses beams of electrons, which are fired at multiple angles, to image specimens kept at minus 150 degrees Celsius. The resulting 'slices' of data are reconstructed into 3-D models on computer.
