Deliberately Transferring a Gene from One Species to Another Is

Question

Deliberately transferring a gene from one species to another is an example of
A)constructing a gene library.
B)genetic engineering.
C)the polymerase chain reaction.
D)cloning.

Accepted Answer

Genetic engineering involves transferring a gene from one species to another, often for the purpose of improving or modifying an organism's traits. Constructing a gene library involves creating a collection of genetic information from a particular organism or group of organisms. The polymerase chain reaction is a laboratory technique used to amplify DNA sequences. Cloning involves creating genetically identical copies of an organism.
