Apr 4, 2024 · As viruses move from person to person in search of survival, they can mutate—or change—over time. This article discusses how viruses mutate, how mutation can affect vaccines, and what viral mutation means as it relates to COVID-19. janiecbros / Getty Images.
Dec 14, 2021 · Mutation is part of being a virus. Viruses mutate to adapt to their surroundings and more effectively move from host to host. Mutations can cause viruses to better evade our immune systems, treatments and vaccines.
Mar 21, 2022 · Viruses with mutations in their genetic code are called variants. Variant refers to the differences in the genetic code from that of the original virus, but strain refers to a different physical property or behaviour exhibited by the virus.
Jun 9, 2021 · As the COVID-19 pandemic continues, new variants of the SARS-CoV-2 virus pop up, and some lead to increasing infections. The main new variants—named Alpha, Beta, and Delta and first identified in Britain, South Africa, and India, respectively—have properties that make them more successful in transmitting and replicating than the original virus.
Feb 11, 2021 · A variant is referred to as a strain when it shows distinct physical properties. Put simply, a strain is a variant that is built differently, and so behaves differently, to its parent virus....
Sep 25, 2024 · Mutation, an alteration in the genetic material (the genome) of a cell of a living organism or of a virus that is more or less permanent and that can be transmitted to the cell’s or the virus’s descendants. The genomes of organisms are all composed of DNA, whereas viral genomes can be of DNA or RNA.
Jan 6, 2021 · The variants have different origins but share a mutation in a gene that encodes the spike protein, which the virus uses to latch on to and enter human cells.
