D) RNA interference
E) An expression vector

Question

Quizplus · Accepted Answer

An expression vector, which is a DNA molecule capable of carrying the gene of interest for protein production and can be efficiently replicated in host cells, would be the most useful tool for large-scale commercial production and harvesting of proteins. The gene of interest can be inserted into the vector and expressed in an appropriate host cell line to produce the desired protein at high yield. This method is widely used in the biotechnology industry as a cost-effective way of producing large quantities of recombinant proteins. Genomic libraries, microarrays, miRNA, and RNA interference are useful tools for studying gene expression and regulation but are not directly applicable to protein production on a large scale.
