New images capture virus in extraordinary detail
.... The photographs clearly show a long coil of DNA dangling inside the viral shell, waiting to be ejected via a protein channel just inside the shell exterior. "Now you can see the end of the DNA. You can see the cylinder holding it, poised to go into the cell," said King. To create the detailed images, the ......of two different kinds of single dendrimers, these dangling lengths of DNA, typically 34-66 bases long, found complementary sequences on other dendrimers and knitted together, forming barbell shaped two-dendrimer complexes with folate on one end and fluorescence on the other end. Folate receptors are over-ex...
