A: The piece of DNA would be able to multiply itself independently in the progeny cells of the organism.
B: It may get integrated into the genome of the recipient.
C: It may multiply and be inherited along with the host DNA.
D: The alien piece of DNA is not an integral part of chromosome.
E: It shows ability to replicate.

The following diagram showing restriction sites in E.coli cloning vector pBR322. Find the role of 'X' and 'Y' genes :
1. The gene 'X' is responsible for controlling the copy number of the linked DNA and 'Y' for protein involved in the replication of Plasmid.
2. The gene 'X' is 'for protein involved in replication of Plasmid and 'Y' for resistance to antibiotics.
3. Gene 'X' is responsible for recognition sites and 'Y' is responsible for antibiotic resistance.
4. The gene 'X' is responsible for resistance to antibiotics and 'Y' for protein involved in the replication of Plasmid.
