Which of the following should be chosen for best yield if one were to produce a recmobinant protein in large amounts ?

Options

A. Laboratory flask of largest capacity
B. A stirred-tank bioreactor without in-lets and out-lets
C. A continous culture system
D. Any of the above.

Explanation

To determine the best choice for producing a recombinant protein in large amounts, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Recombinant Protein Production**:
- Recombinant proteins are produced by expressing a gene of interest in a host organism (heterologous host). The goal is to obtain high yields of the desired protein.

2. **Identify Culturing Methods**:
...
