Question

To amplify and express a gene of interest, it must first be cut out of the chromosomal DNA and inserted into what? A) restriction enzyme B) agarose gel C) vector D) none of these

Answer 1

Inserted into a vector so it can be inserted into another gene.

Answer 2

The right answer is C) vector

In molecular biology and genetic engineering, vectors are DNA molecules that allow the propagation of sequences of interest. These are chimeric DNA molecules such as plasmids or artificial bacterial chromosomes, containing an origin of replication and one or more genetic markers. The origin of replication allows the maintenance of the vector in the target cell during generations.
