The researchers found RNA, but that was not enough to conclude that the RNA was archaeal RNA viruses. Based on the introductory passage and your knowledge of viruses, what evidence showed that the RNA was likely from archaeal RNA viruses? Full genomes were assembled for the study and provided evidence. Analysis showed that the RNA contained the genes for an enzyme that is an RNA-dependent RNA polymerase. The researchers found gene sequences for large protein molecules that needed to be cut by proteases to form smaller functional proteins. The RNA genomes were similar to those of eukaryotic and bacteriophage RNA viruses. Full genomes were assembled for the study and provided evidence. There was RNA present, and that would not normally be in an archaeal community, The archaeal viruses described in the introduction were plus sense, Viruses can be single-or double-stranded, plus sense or minus sense, and they can be characterized as DNA or RNA viruses. These differences can be used in classification. Solution Ans part A options A, B and C are correct Archae constitute a domain of single celled organisms, whose shape and morphology though resembled that of bacteria, but the genome was more similar to eukaryotes. They have circular chromosomes and perform transcription and translation similar to eukaryotes. Even the RNA polymerase resembles to the one present in us..
