1.	Question : Give reasons: a) Plasmids are suitable for use as a vehicle DNA. B) Restriction endonucleases are used in genetic engineering. C) Recombinant DNA is formed of DNA from two sources.
Answer» Solution :a) Plasmids are separate from the main genome and can be easily isolated and introduced. b) RESTRICTION endonucleases cut the DNAs from different sources in such a way as to produce single stranded free ends (STICKY ends) that can UNDERGO complementary pairing to form a recombinant DNA. C) Recombinant DNA technology involves transfer of a DNA fragment from donor ORGANISM to the DNA molecule of recipient.
