A bacterial cell was transformed with a recombinant DNA molecule that was generated using a human gene. However, the transformed cells did not produce the desired protein. The reasons could be:
| 1. | Human genes may have intron which bacteria cannot process |
| 2. | Amino acid codons for humans and bacteria are different |
| 3. | Human protein is formed but degraded by bacteria |
| 4. | All of the above |
