The nucleocapsid of the virus contains a double-stranded circular-shaped strand of DNA (Fields Virology, 2013). (kenyon.edu)

The cold virus is one such virus, which can kill off certain types of amoeba, or what are known as enveloped viruses (which do not have any outer layers). (seniorhumor.org)

Conventional methods for detection and discrimination of influenza viruses are time consuming and labor intensive. (cdc.gov)
The as-fabricated Au NP films were further applied to the colorimetric detection of influenza virus. (nature.com)
Through the attachment of the detection unit to the DNA anchors, the assembly of such a sensor resembles a system of building blocks - except that the individual parts are 100,000 times smaller than a human hair," said Sebastian Kruss, professor of physical chemistry at RUB. (photonics.com)

The ability to custom-make novel protein containers, fibrils, and channels will have major impact on nanobiotechnology. (lu.se)

Due to viruses' rapid evolution, a single clinical sample often contains a mixture of many closely related viruses. (biomedcentral.com)
Granuloviruses are well known for their unique ability to completely liquify their hosts in order to spread to more hosts, a trait they share with the closely related nuclear polyhedrosis viruses. (kenyon.edu)
