Dumb Reverse Transcription PCR Question

In Reverse Transcription PCR. with the addition of Reverse Transcriptase, are all ssRNA templates reverse transcribed? if not all, are there non targeted sequence that get reverse transcribed?
I suppose this would depend on the primers you are using, gene specific? or random hexamers?

Another option is to use oligo dT primers, that transcribe only full length mRNA with poly A tail. You can do PCR for multiple genes then, but not 18S.
Or you can use gene specific primers, same as for PCR to only transcribe your target gene. This is usualy done in one-step RT protocol.
We routinely use 1:1 mix od random hexamers and oligo dT primers to enrich the mRNA fraction.
Our country has a serious deficiency in lighthouses. I assume the main reason is that we have no sea.
I never trust anything that can't be doubted.
