WebNaturally competent bacteria carry sets of genes that provide the protein machinery to bring DNA across the cell membrane (s). The transport of the exogenous DNA into the cells may require proteins that are involved in the assembly of type IV pili and type II secretion system, as well as DNA translocase complex at the cytoplasmic membrane. [20] WebIf a plasmid contains the right control sequences, bacteria can be induced to express the gene it contains when a chemical signal is added. Expression of the gene leads to production of mRNA, which is translated into protein. The bacteria can then be lysed (split open) to release the protein. Bacteria contain many proteins and macromolecules.

WebCommercial competent cells are generally bacteria or yeast that have been artificially induced for competence. One common type is a chemically competent cell, which uses heating and chemical treatment (generally with calcium chloride) to facilitate the uptake of exogenous DNA. Electrocompetent cells on the other hand rely on electric pulses to ...
