The correct Answer is:
To arrange the steps in creating genetically modified organisms in the correct sequence, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the DNA with Desirable Genes (Step C)**: The first step in creating genetically modified organisms is to identify the DNA that contains the desirable genes. This involves selecting the specific genes that will provide the desired traits in the organism. 2. **Introduce 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's cells. This can be done using various techniques, such as transformation, transfection, or using vectors. 3. **Maintain the Introduced DNA in the Host and Transfer to Progeny (Step B)**: After the DNA has been successfully introduced into the host, it is crucial to maintain this DNA within the host cells. Additionally, the introduced DNA must be transferred to the progeny during reproduction, ensuring that the desired traits are passed on to the next generation. ### Correct Sequence: The correct sequence of steps is: - (C) Identification of DNA with desirable genes - (A) Introduction of the identified DNA into the host - (B) Maintenance of introduced DNA in the host and transfer of the DNA to its progeny ### Final Answer: The correct order is C, A, B. ---
