Virus Mutation?<\/strong><\/p>\n\n\n\n

Viral mutations occur when viruses, which cannot reproduce on their own, infect a host and use the host\u2019s cellular machinery to reproduce themselves. During this process, the genome, which is made of either DNA or RNA, depending on the type of virus, is replicated (copied). When the genome of any species is copied, errors naturally and randomly occur. Such errors, or mutations, may be insignificant and have no effect on the organism\u2019s ability to survive. Other mutations, however, may either strengthen or weaken the organism by increasing or decreasing its ability to survive. Those mutations which help an organism to survive and thrive will tend to be passed on to subsequent generations and may become the dominant variant. This is how genetic evolution occurs.\u00a0<\/p>\n\n\n\n

Variations?<\/h2>\n\n\n\n

Mutations occur especially frequently in viruses, because viruses mutate so quickly. RNA viruses<\/strong> are particularly prone to such replication errors, because viral RNA, unlike human DNA, generally lacks an error correcting mechanism. Interestingly, the coronavirus<\/strong> is somewhat different. Although it is an RNA virus, the coronavirus has an enzyme which can correct some replication errors. This makes the coronavirus more stable, and this made it easier for scientists to develop a coronavirus vaccine. The influenza<\/strong> virus is a more typical RNA virus in that it mutates very rapidly, which is why a new influenza vaccine is designed every year to protect us against new variants.<\/p>\n\n\n\n
