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 | |
