2017 Biotechnology: Principles and ProcessesDownstream processing Easy Question 1 of 2 in Downstream processing

The process of separation and purification of expressed protein before marketing is called

A Upstream processing
B Downstream processing
C Bioprocessing
D Postproduction processing

The answer is B.

Solution

Separation and purification = downstream processing.

The biosynthetic stage for synthesis of product in recombinant DNA technology is called upstream processing; after it, the product is subjected to a series of processes including separation and purification, collectively referred to as downstream processing.
