I apologize if the question is so naive (I'm a computer sciences engineer and I have not enough notions in biology and lab experiments). I have RNASeq data coming from the sequencing of 22 patients, for each patient two tissues are sequenced the normal and the tumor tissue, so we have 44 samples (22 tumors, 22 matched normal).
My question is about technical and biological replicates. In my case can I say that we have technical replicates if we consider a single patient because the two samples are grown in the same biological conditions (so, one tissue in control and one tissue in case condition), and biological replicates if we focus on all the patients because the samples are grown in different biological conditions (so, we have 22 replicates in each condition case and control).
Is this correct ?
