This set of Agricultural Biotechnology Multiple Choice Questions & Answers (MCQs) focuses on “Gene Cloning Vectors – Plant Vectors”.
1. Plant transformation vectors (PTV) are termed as binary vectors.
a) True
b) False
View Answer
Explanation: Plant transformation vectors (PTV) are termed as binary vectors. Because of their ability to replicate in multiple hosts.
2. Which of the following are plant transformation methods?
a) Agro bacterium – mediated transformation
b) Protoplast electroporation
c) Gene gun method
d) All the above
View Answer
Explanation: Plant transformation is done by Indirect/vector method and direct method which includes the above mentioned methods.
3. Agrobacterium tumefaciens causes crown gall disease.
a) True
b) False
View Answer
Explanation: Agrobacterium tumefaciens enters plant through wounds in roots or stem and stimulates the plant tissue to grow in a disorganised way, producing swollen galls.
4. Which is the natural genetic engineer from the given examples?
a) Cosmid
b) Bacteriophage
c) Agrobacterium tumefaciens
d) TMV
View Answer
Explanation: Agrobacterium tumefaciens is a Gram negative soil bacterium, which has natural genetic engineering capability by which it integrates its plasmid genes into plant genome.
5. Device designed for delivering exogenous DNA to cells.
a) Gun
b) Gene gun
c) Micro injection
d) Micro projectile
View Answer
Explanation: The gene gun method is used for genetically modifying plants for delivering exogenous DNA to cells.
