In Recombinant DNA Methods, the Term Vector Can Refer To

Question

In recombinant DNA methods, the term vector can refer to
A) the enzyme that cuts DNA into restriction fragments.
B) the sticky end of a DNA fragment.
C) a SNP marker.
D) a plasmid used to transfer DNA into a living cell.
E) a DNA probe used to identify a particular gene.

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.
