D. Isolation of recombinant protein

Options

A. A,B
B. B,C
C. A,B,C
D. A,B,C,D

Answer

To genetically modify an organism, the following steps are involved:

1. **Identification of Desirable DNA**: The first step in genetically modifying an organism is to identify the specific DNA that contains the desirable gene. This gene is the one that will provide the desired traits or characteristics to the organism.

2. **Insertion of DNA into the Host**: Once the desirable DNA has been identified, the next step is to insert this DNA into the host organism's genome. This process often involves the use of vectors, which are vehicles that carry the desired gene into the host cell.

3. **Maintenance of Introduced DNA in the Host**: After the DNA has been inserted, it is crucial to ensure that the introduced DNA is maintained within the host organism. This means that the host must be able to replicate and express the inserted gene properly.

4. **Isolation of Recombinant Protein**: This step is not typically involved in the initial process of genetically modifying an organism. While recombinant proteins can be produced as a result of the genetic modification, the isolation of these proteins is not a necessary step in the modification process itself.

Based on the above steps, the correct answer to the question is A, B, and C.
