Bacteriophage phi29. Cross section computer model of phi29 created using UCSF Chimera molecular modelling software and data from cryo-electron microscopy. Bacteriophages are viruses that infect bacteria. Phi29 only infects Bacillus subtilis. This image shows the empty protein shell, known as the capsid, which normally contains DNA. 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.
