Identify the chief enzyme that is involved in PCR technique.
1 Restriction enzyme
2 DNA ligase
3 Hydrolases
4 Taq polymerase
Explanation:
The enzyme typically used in PCR technique is called Taq polymerase. It is a heat-stable DNA polymerase (isolated from a bacterium Thermus aquaticus), which remain active during the high temperature induced denaturation of double stranded DNA.

Choose the wrong statement regarding the observations drawn from the Human Genome Project
1 Repetitive sequences are stretches of RNA.
2 Less than 2 per cent of the genome codes for protein.
3 Chromosome ' \(\mathrm{Y}\) ' has the fewest number of genes.
4 SNPs help in tracing human history.
5 Repetitive sequences make up a very large portion of the human genome.
Explanation:
Repetitive sequences are stretches of DNA with repeated bases many times in a genome. These sequences are non-coding by nature. Repetitive sequences are not found in RNA.

Suppose DNA samples collected for DNA finger printing analysis are less than the required quantity. Which of the following techniques is helpful to make the samples sufficient for above analysis?
1 Electrophoresis
2 Chromatography
3 PCR
4 DNA probing
Explanation:
PCR (Polymerase Chain Reaction), is a technique which is used to make multiple copies of a segment of DNA. PCR is very much helpful to detect any disease in early stages like cancer and AIDS.

In genetic fingerprinting the 'probe' refers to---
1 A radioactively labelled single stranded RNA molecule
2 A radioactively labelled single stranded DNA molecule
3 A radioactively labelled double stranded DNA molecule
4 A radioactively labelled double stranded RNA molecule.
Explanation:
Probe are small nucleotide sequences use to detect the presence of complementary sequence in nucleic acid sample. Both DNA and RNA are used as probes. Single-stranded DNA probe are more conveniently and preferable but denaturated double stranded DNA molecule can also be used. The probe can either be labelled with radioactive \(\mathrm{P}^{32}, \mathrm{~S}^{35}\) or nonradioactive (e.g. biotin)
