A piece of DNA, somehow transferred into an alien organism, will be able to multiply itself in the progeny cells of organism if:

For the multiplication of any alien piece of DNA in an organism, it needs to be part of a chromosome that has a specific:

In recombinant DNA experiments, a vector:

What controls the copy number of linked DNA if plasmid is used as a vector in bacterial transformation?

What is true for the plasmids used as cloning vectors in recombinant procedures?

The most important feature in a plasmid to serve as a vector in gene cloning experiment is:

1. Origin of replication (ori)

2. Presence of a selectable marker

3. Presence of sites for restriction endonuclease

4. Its size

Some bacteria are resistant to antibiotics. This trait is normally due to:
1. lack of membrane bound organelles
2. presence of a cell wall
3. presence of an extra-chromosomal circular DNA
4. a unique feature called as inclusion bodies

In the given diagram of pBR322, the location of the recognition sequences of BamH I and Sal I are represented by the numbers:

A cloning vector has two antibiotic resistance genes: tetracycline and ampicillin. A foreign DNA was inserted into the tetracycline gene. Non-recombinant transformants would survive on the medium containing:

The Ti plasmid, used in transformation of plant cells, is found in:
