Q8. Protein encoding gene expressed in heterologous host is called as
Answer : Option C
Explaination / Solution:
Recombinant Protein is a protein encoded by a gene — recombinant DNA — that has been cloned in a system that supports expression of the gene and translation of messenger RNA (see expression system). Modification of the gene by recombinant DNA technology can lead to expression of a mutant protein. Protein encoding genes are commonly described as structural or regulatory. Structural gene encodes enzymes and structural protein.
