WebMar 27, 2024 · The two main classes of nucleic acids are deoxyribonucleic acid ( DNA) and ribonucleic acid ( RNA ). DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms and most viruses. WebA bacteriophage, or phage for short, is a virus that infects bacteria. Like other types of viruses, bacteriophages vary a lot in their shape and genetic material. Phage genomes can consist of either DNA or RNA, and can contain as few as four genes or as many as several hundred ^ {1,2,3} 1,2,3 .
