Viral phenomena or viral sensations are objects or patterns that are able to replicate themselves or convert other objects into copies of themselves when these objects are exposed to them. Analogous to the way in which viruses propagate , the term viral pertains to a video, image, or written content spreading to numerous online users within a ...
Viral evolution is a subfield of evolutionary biology and virology that is specifically concerned with the evolution of viruses. [ 1 ] [ 2 ] Viruses have short generation times, and many—in particular RNA viruses —have relatively high mutation rates (on the order of one point mutation or more per genome per round of replication).
Lysogeny, or the lysogenic cycle, is one of two cycles of viral reproduction (the lytic cycle being the other). Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterial cytoplasm. In this condition the bacterium continues to live and ...
Antigenic shift is a specific case of reassortment or viral shift that confers a phenotypic change. Antigenic shift is contrasted with antigenic drift, which is the natural mutation over time of known strains of influenza (or other things, in a more general sense) which may lead to a loss of immunity, or in vaccine mismatch.
For the “Birds Aren’t Real” viral phenomenon, Gaydos and McIndoe concocted fake evidence, a fake history of the movement, and fake documents to support their fake claim, the New York Times ...
To enter the cells, proteins on the surface of the virus interact with proteins of the cell. Attachment, or adsorption, occurs between the viral particle and the host cell membrane. A hole forms in the cell membrane, then the virus particle or its genetic contents are released into the host cell, where replication of the viral genome may commence.
Proponents theorize that memes are a viral phenomenon that may evolve by natural selection in a manner analogous to that of biological evolution. [8] Memes do this through processes analogous to those of variation, mutation, competition, and inheritance, each of which influences a meme's reproductive success. Memes spread through the behavior ...
A man who spent vacation time with his brother in Arizona described what happened after the two of them went on a number of nature hikes — and social media users on Reddit had a field day.
