DNA spliced into plasmid vector?
Foreign DNA is spliced into a plasmid vector. The recombined plasmid then carries the foreign DNA into the bacterial cell, where it replicates independently of the bacterial chromosome. is it True or False?
If the foreign DNA contained a gene for human growth hormone, each cell will make the hormone.

Verified answer
The plasmids have an independent origin of replication, therefore they will replicate independently of the bacterial chromosome. It is true.
For the second question: if the hormone is under the control of a bacterial promoter, then bacteria will express the hormone; if the hormone is under the control of an eukaryotic promoter, bacteria won't express it
Its true, plasmids replicate independently of the bacterial chromosome. Plasmids naturally occur in and exchanged by bacteria.
