Question

what is the reason behind using the foreign DNA in biotechnology​

Answer 1

Answer:

Explanation:

Plasmids have been key to the development of molecular biotechnology. They act as delivery vehicles, or vectors, to introduce foreign DNA into bacteria. Using plasmids for DNA delivery began in the 1970s when DNA from other organisms was first 'cut and pasted' into specific sites within the plasmid DNA.

Answer 2

Few plants doesn’t have desired property or quality which is required by the user. In order to produce that desire quality a cloning vector is been used which will carry the foreign DNA into the host and the plant develop that quality. To ensure that the plant produce that desire quality to offspring it’s should be inserted in ORI (origin of replication)
