Sample questions

1. 1.![pbr322_cloning_vector.png]() In the pBR322 map shown, the restriction site BamH I lies within one of the two antibiotic resistance genes. A foreign DNA ligated at this BamH I site, as drawn in the figure, would insert into the:
   • A.Tetracycline resistance gene (tet R)
   • B.Ampicillin resistance gene (amp R)
   • C.Origin of replication (ori)
   • D.rop gene
2. 2.According to the chapter, the three basic steps in genetically modifying an organism are identification of DNA with desirable genes, introduction of the identified DNA into the host, and:
   • A.Maintenance of introduced DNA in the host and transfer of the DNA to its progeny
   • B.Removal of all native plasmids from the host
   • C.Conversion of the host into a bacteriophage
   • D.Inactivation of the host origin of replication
3. 3.In the naming convention for restriction enzymes, in EcoRI from Escherichia coli RY13, the Roman numeral 'I' indicates:
   • A.The order in which the enzyme was isolated from that strain
   • B.The number of base pairs recognised
   • C.The number of copies per cell
   • D.The number of sticky ends produced
4. 4.In the exercise Describe briefly the following, the origin of replication (ori) is best described as a sequence that:
   • A.Controls the copy number of the linked DNA and from where replication starts
   • B.Codes for an antibiotic resistance protein
   • C.Cuts the DNA at palindromic sites
   • D.Adds methyl groups to the DNA
5. 5.Biotechnology deals with techniques of using live organisms or enzymes from organisms to produce products and processes useful to humans. In its restricted modern sense, biotechnology refers to processes that use:
   • A.Genetically modified organisms to achieve products on a larger scale
   • B.Only wild microbes without any modification
   • C.Only plant tissue culture techniques
   • D.Only chemical catalysts instead of enzymes
