Set 16 Mechanisms Of Genetic Variation

(True False)

Free

Stable integration of foreign DNA into a bacterial host genome is generally accomplished through induced plasmid transformation than by natural uptake of free DNA fragments.

Answer

(True False)

Free

The transformation frequency of very competent cells is about 10^-6,or about 1 in 1,000,000 when an excess of DNA is used.

Answer

(Multiple Choice)

Which procedure is most associated with unsuccessful transformation and degradation of DNA?

A)Naturally-occurring transformation with DNA fragments in competent bacteria.
B)Induced transformation with plasmid DNA in noncompetent bacteria.
C)Integration of DNA fragments in competent bacteria following naturally-occurring transformation.
D)Addition of DNA fragments from competent bacteria to live,noncompetent bacteria without artificial induction.
