Question

Recombination process in a cell occurring through the mediation of phages is called:

• A. Transfection
• B. Transduction
• C. Conjugation
• D. Transformation

Answer 1

The Correct Option is C

The question is about the recombination process in a cell mediated by phages. To understand this, let's briefly discuss the options provided:

1. Transfection: This is the process of introducing nucleic acids into cells. It is mainly used in a laboratory setting to study the function of genes and gene products.
2. Transduction: This refers to the process by which foreign DNA is introduced into a cell via a bacteriophage. In this process, bacteriophages serve as a vector to transfer genetic material from one bacterium to another.
3. Conjugation: This is the direct transfer of DNA from one bacterial cell to another through physical contact, typically involving the formation of a bridge-like connection called a pilus.
4. Transformation: This process involves the uptake of free DNA (often from a lysed cell) from the environment by a bacterial cell.

The correct answer provided in the question is Conjugation, but let's revisit this based on the definition:

The term "recombination process in a cell occurring through the mediation of phages" clearly pertains to Transduction as this process involves phages acting as vehicles to transport genetic material. Hence, the provided correct answer seems to be incorrect.

Therefore, the most appropriate answer according to the definitions and context should be Transduction.

In summary, the recombination process facilitated by phages is known as Transduction, which is different from Conjugation as the latter involves direct contact and not phages.
