Biolistics (gene-gun) is suitable for
1 DNA finger printing
2 Disarming pathogen vectors
3 Constructing recombinant DNA molecules
4 Transformation of plant cells
Explanation:
A Biolistics (gene-gun) is a device used to deliver exogenous DNA, RNA, or protein to cells. In this process, particles of heavy metals are coated with a gene of interest then these microprojectiles are fired into cell using mechanical force for integration of desired genetic information into host cells. This technique is used to transform almost all type of cells (Plant cell, Human cell etc).

The plasmid $\mathrm{P}^{\mathrm{BR}} 322$ used in biotechnology is:
1 yeast
2 $\mathrm{M}^{32}$ Phage
3 parasite
4 cloning vehicle
Explanation:
The plasmid $\mathrm{P}^{\mathrm{BR}} 322$ used in biotechnology is cloning vehicle. A cloning vehicles (vector) is a small piece of DNA that can be stably maintained in an organism, and into which a foreign DNA fragment can be inserted for cloning purposes. The cloning vector may be DNA taken from a virus, the cell of higher organism, or it may be the plasmid of a bacterium.

Which of the following tools of recombinant DNA technology is wrongly paired with its use?
1 Restriction endonuclease production of DNA fragments from gene cloning
2 DNA ligase Enzyme that cuts DNA producing sticky ends
3 DNA polymerase Copies DNA sequences in the PCR
4 Reverse transcriptase Production of $\mathrm{cDNA}$ from mRNA
Explanation:
DNA ligase is the molecular glue in Recombinant DNA Technology (RDT) it joins the fragment together by addition of required nucleotide like A,T,G and C.

DNA fragments generated by the restriction endonucleases in a chemical reaction can be separated by:
1 Restriction mapping
2 Centrifugation
3 Polymerase chain reaction
4 Electrophoresis
Explanation:
Electrophoresis is a technique use to separate DNA fragments according to their size. DNA sample are located into wells (indentation) at one end of the gel and the electric current is applied to poll them through the gel. DNA fragments are negatively charge, so they move towards the positive electrode.
