The question asks about a process in RT-PCR where RNA is converted to DNA by removing the 2' -OH group on the ribose. This is the hallmark of reverse transcription, not transcription or translation. 
Option 1: 'RNA is not converted to DNA the genetic information is transferred.' This statement is inaccurate because RT-PCR explicitly involves converting RNA into DNA to enable amplification; it also misunderstands the direction of information flow in this context. 
Option 2: 'Transcription' refers to RNA synthesis from a DNA template, not RN A-to-DNA conversion, so it does not describe the step occurring in RT-PCR that creates DNA from RNA. 
Option 3: 'Reverse transcription' is the process by which RNA is reverse-transcribed into complementary DNA (cDNA) by removing the 2' hydroxyl group during synthesis, aligning with the described mechanism in RT-PCR. 
Option 4: 'Translation' is the process of synthesizing protein from an mRNA template, which is unrelated to nucleic acid synthesis from RNA to DNA, so it is not the correct description here.
