WebA virus is a tiny, infectious particle that can reproduce only by infecting a host cell. Viruses "commandeer" the host cell and use its resources to make more viruses, basically reprogramming it to become a virus factory. Because they can't reproduce by themselves (without a host), viruses are not considered living.Nor do viruses have cells: they're very … WebFeb 5, 2024 · Without genetic mutations, there would be no humans.

WebRapid change in circulating flu viruses is known as antigenic shift. Shift can happen in several ways: when a flu strain jumps to a species which it has never before infected, or when the process of viral reproduction creates a novel strain. In either case, the human immune system perceives the strain as unfamiliar. WebGenetic recombination was first defined by studies of Drosophila, on the basis of the observation that genes on different copies of homologous chromosomes can reassort during meiosis.
