Repeated transfusions of genetically modified cells are required in $SCID$ patients and in enzyme replacement therapy because
Transfused cells have a limited life span
Introduced gene has been mutated
The enzyme required is degraded after $20\; days$ of transfusion
Both $(a)$ and $(c)$
Taking examples under each category, discuss upstream and downstream processing.
Hybridomas are result of the fusion of
The critical research areas of biotechnology are
$I$. providing best catalyst as improved organism, usually a microbes or pure enzyme
$II$. creating optimal conditions by engineering for a catalyst to act
$III$. down stream processing technologies
$IV$. Multiple Ovulation Transfer Technology $(MOET)$
