Detailed explanation-1: -Traditional genetic modification methods that have been employed-particularly for microbial starter cultures-include selection, mutagenesis, conjugation, and protoplast fusion, the last of which is analogous to somatic hybridization in plant systems.
Detailed explanation-2: -The seven techniques are: (1) Agarose Gel Electrophoresis (2) Isolation and Purification of Nucleic Acids (3) Isolation of Chromosomes (4) Nucleic Acid Blotting Techniques (5) DNA Sequencing (6) Alternative Methods of DNA Sequencing and (7) Chemical Synthesis of DNA.
Detailed explanation-3: -In medicine, genetic engineering has been used to mass-produce insulin, human growth hormones, follistim (for treating infertility), human albumin, monoclonal antibodies, antihemophilic factors, vaccines, and many other drugs. In research, organisms are genetically engineered to discover the functions of certain genes.
