Which of the following is not a feature to facilitate cloning into a vector?

1.      Origin of replication

2.      Selectable Marker

3.      Multiple cloning site

4.      Virulence region

If I want to check the expression of my gene, then I should use

1.      Vectors supporting high copy number

2.      Vectors supporting low copy number

3.      No need to bother about copy number

4.     Vectors with strong Ori

Selectable marker helps

1.      To identify transformants

2.      To identify recombinants

3.      To identify non- recombinants

4.      To eliminate transformants

The normal E. coli cells have

1.      Kanamycin

2.      Tetracycline

2.      Multiple cloning site

3.      Few cloning site

4.     No cloning site at all

If the gene of Beta-galactosidase is not inactivated, means there will be color in the colonies of
