The correct Answer is:
To answer the question "Plasmids and …………… have the ability to replicate within bacterial cells independent of the control of chromosomal DNA," we need to identify another entity besides plasmids that can replicate independently in bacteria. ### Step-by-Step Solution: 1. **Understanding Plasmids**: - Plasmids are small, circular DNA molecules found in bacteria. They are capable of replicating independently of the bacterial chromosomal DNA. This characteristic allows them to carry genes that can provide advantages to bacteria, such as antibiotic resistance. 2. **Identifying the Second Entity**: - We need to find another entity that shares the same ability as plasmids. This entity must also replicate independently within bacterial cells. 3. **Considering Bacteriophages**: - Bacteriophages, or phages, are viruses that specifically infect bacteria. Unlike many other viruses that require the host's chromosomal DNA for replication, bacteriophages can replicate within bacterial cells independently. 4. **Conclusion**: - Both plasmids and bacteriophages have the ability to replicate within bacterial cells without relying on the chromosomal DNA of the host. Therefore, the answer to the question is "bacteriophages." ### Final Answer: Plasmids and **bacteriophages** have the ability to replicate within bacterial cells independent of the control of chromosomal DNA. ---
