According to two recent types of research, animals' DNA contains a "graveyard of viruses" that functions behind the scenes to defend them from various illnesses. Non-coding genes in mammals' bodies, which have long been classified as "junk DNA," maybe shielding humans against old viruses, according to the research.
When a virus infects us, it
leaves a portion of itself in our DNA, according to the experts. When DNA is
found in an egg or sperm cell, it is handed down through the generations. These
viral fragments were found in the genomes of 13 marsupial species, including
the tammar wallaby, koalas, opossums, fat-tailed dunnarts, and Tasmanian devil.
These viral particles
were kept for a reason... We would anticipate all DNA to alter throughout
millions of years of evolution. These fossils, on the other hand, have been
preserved and are still entire.
This might be a system that
works in a similar way as vaccination but is passed down the generations. The
cell is vaccinated against future infection by preserving a viral fossil. In
fact, some of the viral bits discovered in various American and Australian
mammals are thought to have entered the animals' DNA during the dinosaur era,
when the South American and Australian land masses were still connected.
It's worth noting that if we can prove it
happened in marsupials, it's possible it happened in other creatures as well,
including humans. So, is there a chance that a future generation of humans will
be immune to Covid19? There appears to be a chance of that happening, but we'll
have to wait for studies to confirm it.
Vaccinations are still the greatest strategy
to tackle the new coronavirus, regardless of what research on genetic protection
to illnesses may show.
