Which one of the following statement is not true regarding gel electrophoresis technique?
1 Bright orange coloured bands of DNA can be observed in the gel when exposed to UV light
2 The process of extraction of separated DNA strands from gel is called elution
3 The separated DNA fragments are stained by using ethidium bromide
4 The presence of chromogenic substrate gives blue coloured DNA bands on the gel
Explanation:
The presence of chromogenic substrate gives blue coloured DNA bands on gel is incorrect because as orange bright colored bands of DNA can be observed in the gel when \(\mathrm{EtBr}\) (Ethidium bromide) treated DNA is exposed to UV light.

The device which can remove particulate matter present in the exhaust from a thermal power plant is :
1 Catalytic Convertor
2 STP
3 Incinerator
4 Electrostatic Precipitator
Explanation:
The device which can remove particulate matter present in the exhaust from a thermal power plant is electrostatic precipitator. The electrostatic precipitator removes over \(99 \%\) of particulate matter present in the exhaust from a thermal power plant. It has electrode wire that are maintained at several thousand volts, which produce a corona of electrons.

Which of the following enzymes cut the DNA molecule at specific nucleotide sequence
1 Restriction endonuclease
2 DNA ligase
3 RNA polymerase
4 Exonuclease
Explanation:
Restriction enzymes found naturally in bacteria can be used to cut DNA fragments at specific sequences, while another enzyme, DNA Ligase, can attach or rejoin DNA fragments with complimentary ends.

PCR is associated with
1 DNA cloning
2 Amplification of DNA
3 DNA selective replicaiton
4 All of the above
Explanation:
PCR stands for polymerase chain reaction. It is a technique to make multiple copies of the gene (or DNA) of interest in vitro by using two sets of primers and the enzyme DNA polymerase. In this process replication of DNA is repeated many times, the segment of DNA can be amplified. Such repeated amplification is achieved by the use of a thermostable DNA polymerase (isolated from a bacterium, Thermus aquaticus). PCR is related with amplification, DNA cloning and selective replication of DNA molecules.
