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...
Genetic Engineering Explained Genetic engineering is a technique used to deliberately modify a specific characteristic (or characteristics) of an organism. The technique involves removing a gene (o...
Recombinant DNA The genetic code is universal, meaning that almost every organism uses the same four nitrogenous bases – A, T, C & G. There are a few exceptions This means that the same codons ...
