This set of Biochemical Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Cellular Information – Transduction”.
1. ____________ is a novel technique to alter the genetic nature of cells without an physical contact between the vector and host.
a) Transformation
b) Transduction
c) Conjugation
d) Transposons
View Answer
Explanation: Transduction is a technique used for the transfer of a foreign DNA into a host cell with the help of a viral vector. It is one of the most stable methods to transfer DNA.
2. In which year was transduction discovered?
a) 1952
b) 1962
c) 1972
d) 1975
View Answer
Explanation: Transduction was discovered in 1952. Norton Zinder and Joshua Lederberg are the scientists who discovered this technique of gene transfer.
3. Which was the first host cell species used to discover transduction?
a) Escherichia coli
b) Streptococcus
c) Salmonella
d) Staphylococcus
View Answer
Explanation: Transduction was discovered in 1952 in Salmonella. Norton Zinder and Joshua Lederberg are the scientists who discovered this technique of gene transfer.
4. Lysogenic cycle allows integration of phage chromosome with bacterial chromosome by the help of covalent bond formation.
a) True
b) False
View Answer
Explanation: Lysogenic cycle allows integration of phage chromosome with bacterial chromosome by the help of covalent bond formation. Lysogen is induced using UV light.
5. DNA insertion to host cell can result in three fates. If a plasmid is inserted then what will be its shape after insertion?
a) Linear
b) Spherical
c) Circular
d) Tubular
View Answer
Explanation: If a plasmid is inserted then it will re-circularize upon the insertion into the host cell. This makes it a plasmid again.
6. What is the peculiarity of the plasmids used in transduction?
a) All plasmids contain sequence for virus formation
b) No plasmid contain sequence for virus formation
c) All plasmids contain sequence for inactivate virus formation
d) No plasmid contain sequence for virus lysis
View Answer
Explanation: No plasmid contains any genomic sequence for the formation of virus. Multiple plasmids should be used to get an infected virion.
7. Transduction can provide resistance to Antibiotics.
a) True
b) False
View Answer
Explanation: Transduction can provide resistance to Antibiotics. This technique can be used in gene therapy.
