The correct Answer is:
To arrange the steps in genetically modifying an organism in the correct sequence, we need to follow the logical order of the processes involved in genetic engineering. Here are the steps: 1. **Identification of DNA with desirable genes (Step C)**: The first step in genetically modifying an organism is to identify the DNA that contains the desirable genes. This involves selecting the specific gene or genes that will be introduced into the host organism. 2. **Introduction of the identified DNA into the host (Step A)**: Once the desirable DNA has been identified, the next step is to introduce this DNA into the host organism. This can be done using various methods such as transformation, transfection, or microinjection, depending on the type of organism being modified. 3. **Maintenance of introduced DNA in the host and transfer of the DNA to its progeny (Step B)**: The final step involves ensuring that the introduced DNA is maintained within the host organism. This includes the replication of the DNA during cell division and ensuring that it is passed on to the progeny of the host organism. Thus, the correct sequence of steps is: 1. (c) Identification of DNA with desirable genes 2. (a) Introduction of the identified DNA into the host 3. (b) Maintenance of introduced DNA in the host and transfer of the DNA to its progeny
