Answer:
b. the foreign DNA is integrated into one of the cell's chromosomes.
Step-by-step explanation:
The transformation of a cell is generally considered to be successful if the foreign DNA is integrated into one of the chromosomes of the cell.
Gene or genetic transformation is a process during which a foreign gene (DNA) is introduced into the genome of a host organism using a vector DNA.
The vector DNA is first infused with the gene of particular interest in order to make a recombinant DNA. The recombinant DNA is then introduced into the cell that is to be transformed.
Successful transformation will see the gene of particular interest (the foreign DNA) integrated into one of the chromosome of the cell.
The correct option is b.
