Gel Electrophoresis Gel electrophoresis is a technique used widely in the analysis of DNA, RNA and proteins. During electrophoresis the?molecules?are?separated?according to their?size / mass?and th...
Polymerase Chain Reaction (PCR) Polymerase chain reaction?(PCR) is a common molecular biology technique used in most applications of gene technology, for example, DNA profiling (eg. identification ...
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...
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?...
