A distinct advantage of continuous culture over batch culture is
(1) Higher productivity
(2) Versitality
(3) Can be used for different reactions everyday

Why is a marker gene useful?
1. It shows you whether the gene being added, has been taken up or not.
2. It's a way of labelling which gene you want to modify.
3. It sticks with the striker gene.
4. It marks the position of r-DNA
Transformation is the term used to denote
(1) Non virus mediated gene transfer in non Animal eukaryotic cells
(2) Virus mediated gene transfer in Bacteria
(3) Virus mediated gene transfer in non Animal eukaryotic cells
(4) All of the above
