What's Happening?
Viruses remain one of the most enigmatic entities in biology, with ongoing debates about their classification as biological or chemical agents. They are obligate parasites, requiring living cells for reproduction, and have played a crucial role in genetic engineering advancements, such as CRISPR technology. Viruses contain either DNA or RNA within a protein shell and infect all life forms, sometimes jumping between species. Despite their small size, viruses can remain dormant for extended periods and become virulent upon exposure to hosts. The origins of viruses are still uncertain, with hypotheses suggesting they evolved from self-replicating chemicals, mobile genetic elements, or regressive intracellular bacteria.
