Recombinant Human Proteins DNA that has been altered by introducing nucleotides from another source is called recombinant DNA (rDNA) If the organism contains nucleotides from a different species it...
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), ...
