Thank you... a bit over my head (I majored in Computer Sci, not Biology) but still enlightening; I could still follow a lot from context. To sum up, am I correct in saying that all nucleoSide RT inhibitors must be metabolized (phosphorylated) into nucleoTide form before they are active? And that Adefovir, already being in nucleoTide form (or very similar), doesn't have to go thru this conversion? Is there any benefit to this? Do ALL (current) RT inhibitors (Side & Tide) eventually function the same way? Which, if I understand it correctly, is to mimic true nucleotides and, during transcription by RT reading the viral RNA, be attached to the viral DNA chain under construction and terminate it? And, since the RTI is an analogue & not the real thing, no further bases can be attached, therefore leaving an incomplete & presumably non-functional DNA strand?
