The basic technology of genetic engineering is artificial cutting, splicing, and combination of genes. A gene is a DNA molecule with a certain function. To accurately cut out the DNA linear molecular ...

Restriction enzymes are one of the most important tools in the recombinant DNA technology toolbox. But how were these enzymes discovered? And what makes them so useful? Aa Aa Aa When I come to the ...

Scientists first observed the biological phenomenon of restriction and modification in the 1950s, but they did not identify and isolate restriction enzymes until the late 1960s. 3 In 1970, Hamilton ...

Restriction fragment length polymorphism (RFLP) is a technique invented in 1984 by the English scientist Alec Jeffreys during research into hereditary diseases. It is used for the analysis of unique ...
