The genes express large polyproteins that undergo proteolysis to form several nonstructural proteins with various functions … Zobacz więcej ORF1a is the first open reading frame at the 5' end of the genome. Together ORF1ab occupies about two thirds of the genome, with the remaining third at the 3' end encoding the structural proteins and accessory proteins Zobacz więcej Core replicase domains A set of five conserved "core replicase" protein domains are present in all nidovirus lineages (arteriviruses, mesoniviruses, roniviruses, … Zobacz więcej The polyproteins pp1a and pp1ab contain about 13 to 17 nonstructural proteins. They undergo auto-proteolysis to release the nonstructural … Zobacz więcej The structure and organization of the genome, including ORF1a, ORF1b, and the frameshift separating them, is conserved … Zobacz więcej

It indicates an estimate of how much virus was likely in the sample to start with – not the actual amount. If the virus is found in a low number of cycles (Ct value under 30), it means that the virus was easier to find in sample and ...
