Which one of the following is a case of wrong matching?
1 Micropropagation-Invitro production of plants in large numbers
2 Callus-Unorganised mass of cells produced in tissue culture
3 Somatic hybridization-Fusion of two diverse cells
4 Vector DNA-Site for t-RNA synthesis
Explanation:
Vectors are DNA molecules that can carry a foreign DNA segment and replicate inside the host cell. They are used in recombinant DNA technology. Hence, vector DNA site for t-RNA synthesis is wrong matching.

Which one is a true statement regarding DNA polymerase used in PCR?
1 It is isolated from a virus
2 It remains active at high temperature
3 It is used to ligate introduced DNA in recipient cells
4 It serves as a selectable marker
Explanation:
DNA Polymerase is heat stable enzyme used for polymerisation or amplification. In PCR, Taq polymerase is used which is obtained form thermo aquatic bacteria is a thermostable DNA polymerase. It remains active at high temperature.

Identify the correct combination of the following related to recombinant DNA technology.
1 Ti plasmid - Artificially synthesized plasmid
2 DNA probe - Radioactively labelled double stranded DNA
3 Sticky ends of DNA - Facilitate the action of DNA Ligase
4 Colony hybridization - Identification of antibiotic resistant gene
Explanation:
The Sticky ends of DNA facilitate the action of DNA ligase. - Ti plasmid - Ti plasmid is a natural plasmid. Tumor inducing plasmid, is found in a pathogenic species of agrobacterium. - DNA probe - A probe is a single-stranded sequence of DNA or RNA used to search for it complementary sequence in a sample genome. - Colony hybridization - Colony hybridization is a method of selecting bacterial colonies with desired genes. It is no use for identification of antibiotic resistance gene.

The function of polymerase chain reaction is
1 transduction
2 DNA amplification
3 translation
4 None of these
Explanation:
PCR was discovered by Carry Mullis, in Polymerase Chain Reaction (PCR) a segment of DNA is amplified. Tag DNA polymerase enzyme is use in PCR. This enzyme is temperature resistant.
