Question # 1

Define genomic library,how it can be made?

  • Ans 1: A genomic library is a collection of bacterial or bacteriophage clones,each containing a particular segment of DNA from the source cell.
    For making genomic library,an organism's DNA is simply sliced up into pieces and pieces are put in to vectors that are taken up by the host bacteria.The entire collection of bacterial or bacteriophage clones that result contains all the genes of that organisms.

Question # 1

Define gene therapy.Name two main methods of gene therapy.

  • Ans 1: Gene therapy is the insertion of genetic material into human cells for the treatment of a disorder.It includes procedures that give a patient healthy genes to make up for faulty genes and also includes the use of gene to treat various other human illnesses such as cancer and cardiovascular diseases.
  • Ans 2: There are two main methods used for gene therapy:
    Ex-vivo and In-vivo gene therapy.
