what's your favorite standard RNA nucleobase? disclaimer: i am fully aware that RNA and DNA have numerous other differences (like the extra hydroxyl group, their differential ability to fold into secondary structures as well as their catalytic abilities as ribozymes vs dnazymes, the numerous roles of non-coding RNA...) as well as surprising similarities (genomic RNA used by some viruses, double stranded RNA in both viral contexts and beyond...). this is a trend (please someone get the reference)

⚠️ Do not self diagnose! ⚠️ although these images are fairly representative, many skin conditions can look similar, and diagnosis often requires examination (sometimes with dermoscopy or even a biopsy). For example, not every dark mole is melanoma, and not every red scaly patch is eczema or psoriasis! If you notice something unusual on your skin seek professional help. #skinhealth #healtheducation #skinconditions
