Question: What process requires contact between the donor cell and the recipient cell? A. transformation B. transduction C. transcription D. conjugation
Answer: D. conjugation
Conjugation process requires direct contact between a donor cell and a recipient cell. Conjugation is a horizontal gene transfer method by which bacterial cells transfer genetic material from one cell to other by direct cell-to-cell contact. Transfer of the genetic material from one cell to the other occurs through a bridge-like connection called conjugation pillus. Thus to transfer the genetic material by conjugation requires direct contact between a donor cell and a recipient cell. Other horizontal gene transfer mathods that occurs in bacterial cells are: transformation, and transduction. Transformation is the process in which bacterial cells take up foreign genetic materials from surrounding environment. Transduction is the process in which the transfer of genetic material occurs between one bacterial cell to the other by a virus (bactriophage).
Transcription is the first stage of the gene expression process by which DNA is copied to mRNA, the second stage is the translation process.

Please classify each statement as describing transformation, conjugation, or transduction in bacteria. Bacteria can acquire plasmids from outside the cell. A bacterium that contains an F plasmid connects to a recipient bacterium that lacks an F plasmid with an appendage called a pilus, through which the plasmid is transferred. Some bacterial DNA fragments may be included when new phage particles are assembled. A cell can be treated to make it competent to take up DNA from its environment. When a...
