You are absolutely right,Intrond are often not necessary for the expression of a cDNA in transfected cells. However, in transgenic animals,GTCB use the goat casein gene (that has enough introns in it) into which they inserted their cDNA and that construct allow a high and reliable expression of the foreign gene.
