Molecular biotechnology is basically the study and alteration of nucleic acids and proteins in living organisms for various applications. It encompasses the different scientific fields of genetics, engineering, chemistry, microbiology, etc. Because of this, all of the given choices are methods of molecular biotechnology EXCEPT DNA profiling.

Answer:

All the given options except selective breeding are the methods of molecular biotechnology.

Molecular biotechnology refers to the study and modification of proteins and nucleic acids with the help of laboratory techniques.

It creates many applications in the field of medicine, agriculture, animal health, and the environment.

It mainly involves the modification and introduction of a foreign gene into an organism in order to produce desirable products.

Thus, recombinant DNA, molecular hybridization, cloning, induced mutation, DNA profiling all come under this steam.

In contrast, elective breeding is not an example of molecular biotechnology as it does not include modification at molecular level. It is a method used in used in genetics in order to produce offspring with desired character.
