Is option 1 true or false?
Transfected B cells will not become immortalized. It is
immortalized when the B cell contain EBV episomes along with 9
virus encoded protein--> false?---> answer C
The Dr. is altering a virus encoding protein and for this to
happen i'm assuming he would do this in vitro so they will become
immortalized. Earlier in the problem it states "B lymphocytes inf.
with EBV & grown in vitro are immortalized & termed LCL
which contain...
