Transfer of genetic information from one bacterium to another in the transduction process is through:
Correct answer: A. Bacteriophages released from the donor bacterial strain.
- A. Bacteriophages released from the donor bacterial strain.
- B. Another bacterium having special organ for conjugation.
- C. Physical contact between donor and recipient strains.
- D. Conjugation between opposite strain bacterium.
Explanation
The transfer of genetic information from one bacterium to another in transduction occurs through bacteriophages. Let's explain each option and provide the correct answer with details: Bacteriophages released from the donor bacterial strain: This is the correct answer. Transduction is a method of horizontal gene transfer in bacteria where genetic material is transferred from one bacterium to another via a bacteriophage. Bacteriophages are viruses that infect bacteria and can carry bacterial DNA from one host to another during the infection cycle. Another bacterium has a special organ for conjugation: This option refers to conjugation, which is another method of horizontal gene transfer in bacteria. Conjugation involves the direct physical contact between two bacterial cells and the transfer of genetic material through a conjugation pilus. It is different from transduction. Physical contact between donor and recipient strains: While physical contact is essential for conjugation, it is not how transduction works. Transduction involves the use of bacteriophages to transfer genetic material, and it does not rely on direct physical contact between the donor and recipient strains. Conjugation between opposite strain bacterium: This option also describes conjugation, which is a different process from transduction. Correct Answer: The transfer of genetic information from one bacterium to another in the transduction process occurs through "a. Bacteriophages released from the donor bacterial strain." Summary: Transduction is a process of genetic transfer in bacteria in which bacteriophages (viruses that infect bacteria) carry bacterial DNA from a donor bacterium to a recipient bacterium. It is a mechanism of horizontal gene transfer and plays a role in bacterial evolution and genetic diversity. Conjugation, on the other hand, involves direct physical contact between bacterial cells and the transfer of genetic material through a conjugation pilus.
