comment what is the difference between “cistron” and “gene”
off the top of my head: cistron and gene are equivalent to each other but cistron is a bit old-fashioned. Consider two phenotypes in different individuals belonging to certain organism; let's say both of them are recessive and you cross these phenotypes with one another. If you see wild type phenotype in the next offspring then it means your phenotypes reside in different regions in the genome and these regions were first defined as cistrons. Of course it then turned out to be much more complicated than that and people started using the term gene more often
comment What is Pan for in pan-caspase?
there is no specific context but i now realized that it is usually used as pan-caspase inhibitor in the articles i was looking at. just to be sure: can we then say that pan is the opposite of specific?
