Modern biology is very much not an exception to the central dogma; it still remains central. Don't mistake the vehemence of the RNA biologists (of which I used to be one) for impact or significance (for example, the central dogma had no opinion of whether the ribosome was a protein machine, or an RNA machine, or a protein-RNA machine where RNA formed the critical core components).

The only really important detail that wasn't in the original dogma is reverse transcriptase, and they added a dotted line to support that once it was found in physical form.
