Plasmid. A plasmid is a small circular DNA presents in bacterial cells. It is used as a cloning vector for DNA. The cloned DNA and the plasmid are treated with a restrriction enzyme. The enzyme will make cleaveges in the same portions of the two DNA. The plasmid is then allowed to be replicated inside the bacterial cell.
Having a karyotype done is important to detect crucial diseases such as Trisomy 13, Trisomy 21, Klinefelter's Disease, and Turner syndrome.
