Gene Editing Gene?genome?editing?(or editing) allows genetic engineers to alter the DNA of organisms by?inserting,?deleting?or?replacing?DNA?at specific sites in the genome known to cause disease. ...
Genetic Engineering: Promoter The?promoter?(an example of a length of non-coding DNA that has a specific function) is the?region of DNA that determines which gene will be expressed. This is because...
Genetic Engineering: Vectors Vectors are used to?transfer the desired genes?into a foreign cell Plasmids are the most commonly used vector but viruses and liposomes (a small vesicle with a phosphol...
Genetic Engineering: Enzymes Genetic engineering is the deliberate modification of a specific characteristic (or characteristics) of an organism. The technique involves?removing a gene?(or genes), ...
Isolating the Desired Gene The gene with the specific characteristic that is required can be obtained in the following ways: Extracting the gene from the DNA of a donor organism using enzymes (rest...
