All of the Following are Characteristics That Make Plasmids Good

Question

All of the following are characteristics that make plasmids good cloning vectors, except
A)they are small.
B)they are well characterized.
C)they can be transferred into appropriate host cells.
D)they can carry genetic markers, such as antibiotic resistance genes.
E)they can accept a relatively large amount of foreign DNA.

Accepted Answer

Plasmids are generally limited in the amount of foreign DNA they can accept, which is typically less than 10-15 kb for most cloning applications. This limitation is due to the need for efficient transformation into host cells and stable replication within those cells.
