¿Los virus están vivos?

Viruses are ubiquitous, affecting various organisms and even integrating into human DNA. They infect host cells by releasing genetic material, using the cell's machinery to replicate. Viral DNA can integrate into human DNA, potentially being inherited. The origins of viruses are debated, with theories suggesting they predate single-celled organisms. Viruses have significantly impacted human history, notably in epidemics. The debate on whether viruses are alive centers on their lack of metabolism and independent reproduction. Viroids and prions, similar entities, also pose unique challenges. Despite their dangers, viruses have beneficial applications in medicine and agriculture.
