Recombinant DNA is force to enter the host cells by incubating the cells with rDNA first

Recombinant DNA or rDNA technology was discovered by

A method in which recombinant DNAs are incubated with host cells on ice, followed by placing them briefly at 42^(@) C and then putting them back on ice is called:
