WebBacteria can be naturally competent or made competent by artificial methods. The factors that regulate natural competence vary between various genera. The practical approach to acquire competent cells is to make the bacterial cells artificially competent using chemicals or electrical pulses. WebApr 9, 2024 · The bacterial cells which will take up the foreign DNA from the environment by a process called transformation are referred to as competent cells. Griffith first reported it in Streptococcus pneumoniae. In the case of wall alteration, E.coli cells are more likely to uptake the DNA. WebJan 1, 2013 · Step 2 Transform Competent Cells6.1. Overview.
