I contend teaching all this new knowledge is not necessary. Cutting 
down on the physico-chemical nature of interaction between 
biomolecules in order to squeeze the latest on regulation of mRNA 
in Biochemistry course is just plain stupid. 

Kits are clearly a necessity in today's research but the advantage 
they bring comes at the expense of better education. It's got to 
the point that most new students not only dod not know how pH 
electode is calibrated, but they don't know how to use pH meter 

First things to be taught are ones that are needed most, right? 
Well, basic practical skills, thorough understanding of basic 
underlying principles, good analytical skills and healthy 
skepticism is all it takes. With regards to that, nothing 
has changed in biology in the past 20 years.
