What is a t-zone retrovirus? Retrovirus Structure: Retroviruses are double-stranded RNA viruses, meaning their genomes contain two linked strands of RNA rather than the DNA that makes up the human genome. One reason they are hard to detect is that they can be dormant or virtually dormant in...
Rhinoviruses are non-enveloped, single-stranded positive RNA (ss + RNA) viruses that belong to the familyPicornaviridae, genusEnterovirus. There are three major serotypes of rhinovirus (RV), and each utilizes a specific cellular receptor for viral entry – RV-A utilizes intercellular adhesion...
The diversity of viral infections is immense. Viruses cause everything from common cold (rhinoviruses) to Ebola and warts (papillomavirus); from HIV/AIDS to influenza and smallpox. Many viruses can cause cancer: the hepatitis B virus is a known cause of liver cancer, and some types of human...

Dark DNA is the genetic code in the human genome that currently has no known original source. We have traced 8% of the human genome to viruses. 1-2% of our genome comes from other animals. Believe it or not you share 55% of your genetic code with a banana – and that’s not just...
