Bioinformatics The various technologies (eg. microarrays and gene sequencing) being used today to analyse genes and proteins generate enormous quantities of data The data being collected ranges fro...
Microarrays Microarrays are laboratory tools?used to detect the expression?of thousands of genes at the same time and to?identify the genes present?in an organism’s genome Microarrays are used in m...
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...
