Solving time: 4 mins

Palaeontologists unearthed a human skull during excavation. A small fragment of the scalp tissue was still attached to it. Only little DNA could be extracted from it. If the genes of the ancient man need to be analysed, the best way of getting sufficient amount of DNA from this extract is :

A
By hybridizing the DNA with a DNA probe

B
By subjecting the DNA to polymerase chain reaction

C
By subjecting the DNA to gel electrophoresis

D
By treating the DNA with restriction endonucleases

Two enzymes responsible for restricting the growth of bacteriophages in Escherichia coli were isolated. One was methylase and other was restriction endonuclease. What was the significance of methylase?
  1. Able to cut the DNA of bacteriophage at specific sites
  2. Able to remove the methyl group and hence prevent the action of restriction endonuclease on host DNA
  3. Protection of host DNA from the action of restriction endonuclease by adding methyl group to one or two bases.
  4. Able to ligate the two cohesive ends of DNA molecule
