Virus
A noncellular biological entity that can reproduce only within a host cell.

Viruses consist of nucleic acid covered by protein; some animal viruses are also surrounded by membrane. Inside the infected cell, the virus uses the synthetic capability of the host to produce progeny virus.

2. A kind of intracellular parasite that can replicate only inside a living cell. In its dispersal stage between host cells, a virus consists of nucleic acid that codes for a small number of genes, surrounded by a protein coat. (Less formally, according to Medawar’s definition, a virus is “a piece of bad news wrapped in a protein.”)

Vitamin A
A member of a chemically heterogeneous class of organic compounds that are essential, in small quantities, for life.

Von Mutius, Erika
A pediatrician and allergist, Dr. von Mutius’s research interests include the epidemiology of childhood asthma and allergies with a focus on environmental predictors and gene environment interactions.

Vrijenhoek, Robert
A senior scientist in the areas of evolutionary biology, marine biology, and conservation, Vrijenhoek studies the ecological and evolutionary consequences of genetic diversity in animals. His research efforts have focused on the evolutionary and ecological consequences of sexual and asexual reproduction in Meixcan poeciliid fish (genus Poeciliopsis), as well as invertebrates in deep sea hydrothermal vents.
