Explanation are given for understanding. D. transformation. A specialized transducing phage that attacks an infected cell with lysogenic stage of the same virus produces, 3. This process does not require cell-to-cell contact and is resistant to DNase. Mutations. Later this gets integrated into the bacterial genome. All of the following are ways that prokaryotes can exchange genetic material except A. vertical gene transfer. Mutagens and carcinogens. This process was first reported in Streptococcus pneumonia by Griffith. Your email address will not be published. The recipient cell now contains a copy of F plasmid and becomes a donor cell. This set of Microbiology Multiple Choice Questions & Answers (MCQs) focuses on “Bacterial Conjugation”. Specialized transduction B. B) replicates DNA. The virus genome is induced in the host cell genome. Conjugation differs from reproduction because conjugation A) copies RNA to make DNA. This set of Genetic Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Transformation”. Other articles where Conjugation is discussed: antibiotic resistance: Mechanisms of resistance: are transduction and conjugation. Also Read: Difference between Virus and Bacteria. Solve some important questions on transduction for NEET. E) transcribes DNA to RNA. It is ___________ when the phage tranduces those bacterial genes only which are adjoining to the prophage in the bacterial chromosome, 9. except. Required fields are marked *. Thus, the genetic information is transferred from the mother to the offspring and is known as vertical transmission. Horizontal Gene Transfer in Bacteria : Transformation, Transduction and Conjugation Gene transfer in bacteria can be broadly divided into- Vertical gene transfer (transmission of genes from parents to offspring during cell division) Due to this, the phage genome sometimes carries the bacterial genome with it and integrates it into the genome of the recipient cell. Learn more on NEET, at BYJU’S. There are numerous bacteria found on planet earth. Question 18 (1 point) The thermocline in lakes: is present in spring and autumn and the result of the progressive mixing of our waters. There are various conjugal plasmids carried by various bacterial species. Conjugation is the technique of transfer of genetic material from one bacteria to another placed in contact. Through transduction when a recipient bacterial cell picks up bacterial DNA, then, (a) the new DNA replicates every time the recipient undergoes multiplication, (c) the DNA modifies to match/compliment that of the recipient, (d) the new DNA should enter a new bacteriophage or it is lost, 2. They discovered that the F-factor can move between E.coli cells and proposed the concept of conjugation. General transduction C. Abortive transduction D. None of these. The donor and the recipient strand both contain a single strand of the F-plasmid. 30. Not all bacteria are capable of taking up DNA from the surrounding environment. Answer: A. The cells that have the ability to uptake DNA are known as competent cells. In transduction, viruses grab pieces of bacterial DNA from one host cell and deposit it in the next cell they bind to.
