N76 [4]

The given blanks can be filled with the ability to take up foreign DNA and express proteins faster.  

The direct manipulation of the genes of an organism with the application of biotechnology is known as genetic engineering. It is an array of technologies that are utilized to modify the genetic make-up of an organism, involving the transfer of genes across and within the boundaries of the species to generate novel or bettered organisms.  

In genetic engineering, bacteria play a key role, as it is an essential tool for natural scientists. The genes and other genetic information from a broad array of species can be administered into bacteria for modification and storage, thus producing genetically modified bacteria in the procedure.  

The bacteria possess the tendency to take up foreign DNA and expresses the desired proteins at a faster rate.
