Detailed explanation-1: -Gene editing, based on a technology known as CRISPR-Cas9, allows researchers to customize a living organism’s genetic sequence by making very specific changes to its DNA.
Detailed explanation-2: -A transgenic, or genetically modified, organism is one that has been altered through recombinant DNA technology, which involves either the combining of DNA from different genomes or the insertion of foreign DNA into a genome.
Detailed explanation-3: -Recombinant DNA: DNA which has been altered from its original form by joining genetic material from two different sources. It usually involves putting a gene or part of a gene obtained from one organism into the genome of a different organism.
Detailed explanation-4: -Recombinant DNA technology is the joining together of DNA molecules from two different species. The recombined DNA molecule is inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and industry.
Detailed explanation-5: -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.
