Final answer:
The correct answer is 3) Removing the bacteria's ability to produce other proteins.
Step-by-step explanation:
The correct answer is 3) Removing the bacteria's ability to produce other proteins. This step is not necessary when genetically engineering bacteria to produce a human protein.
When genetically engineering bacteria to produce a human protein, the first step is to insert the gene for the human protein into the bacteria's DNA. This can be done through a process called transformation, where the recombinant DNA is inserted into a living bacterial cell.
The second step is to ensure that the gene is expressed by the bacteria. This is important because the gene needs to be transcribed and translated into a functional protein.
The fourth step is to provide the bacteria with the necessary nutrients for protein production. This includes the building blocks (amino acids) required for protein synthesis.
