Question

Quizplus · Accepted Answer

In recombinant DNA methods, a vector is typically a plasmid, which is a small circular piece of DNA that can be used to transfer DNA into a living cell. Plasmids have the ability to replicate independently within a cell, so they can be used to amplify a DNA sequence of interest. Other options such as A, B, C, and E do not accurately describe vectors in recombinant DNA methods.
