Some viruses replicate inside archaea: these are typically DNA viruses with uncommon and in some cases special designs.[four][68] These viruses are already studied for most depth during the thermophilic archaea, notably the orders Sulfolobales and Thermoproteales.[235] Defences against these viruses entail RNA interference from repetitive DNA sequences in just archaean genomes which might be linked to the genes of your viruses.
A virus exists only to reproduce. When it reproduces, particles unfold to new cells and new hosts. The options of a virus influence its capability to distribute.
