• C. The ability to transfer DNA and protein
• D. The ability to transfer specific RNA molecules

Answer: (A)

Verified step by step guidance

1. Understand the concept of transduction: Transduction is a process by which DNA is transferred from one bacterium to another by a virus, known as a bacteriophage.
2. Differentiate between generalized and specialized transduction: Generalized transduction can transfer any part of the bacterial genome, while specialized transduction involves the transfer of specific portions of the bacterial DNA.
3. Focus on specialized transduction: In specialized transduction, the bacteriophage integrates its DNA into a specific site on the host genome. When the phage DNA is excised, it may take adjacent bacterial genes with it.
4. Identify the key feature of specialized transduction: The defining characteristic of specialized transduction is its ability to transfer only specific DNA molecules, typically those near the phage integration site.
5. Review the options provided: Compare the options with the key feature of specialized transduction to determine that it is defined by the ability to only transfer specific DNA molecules.
