A bacterial cell was transformed with a recombinant DNA that was generated using a human gene. However, the transformed cells did not produce the desired protein. Reason could be

Options

A. human gene may have intron which bacteria cannot process
B. amino acid codons for humans and bacteria are different
C. human protien is formed but degraded by bacteria
D. All of the above.

Explanation

To solve the question regarding why a bacterial cell transformed with recombinant DNA containing a human gene did not produce the desired protein, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Transformation Process**:
- A bacterial cell can be transformed with recombinant DNA, which involves inserting a gene of interest (in this case, a human gene) into the bacterial genome or plasmid.

2. **Identifying the Nature of the Gene**:
