Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following terms describes the process of the uptake of recombinant plasmids into bacteria cells?
A
rDNA technology
B
transferrence
C
transformation
D
rDNA plasmid
Explanation: 

Detailed explanation-1: -Once a recombinant plasmid is made that contains a gene of interest, such as insulin, the plasmid can enter bacterial cells by a process called transformation.

Detailed explanation-2: -Bacteria can take up foreign DNA in a process called transformation. Transformation is a key step in DNA cloning. It occurs after restriction digest and ligation and transfers newly made plasmids to bacteria.

Detailed explanation-3: -(1) Isolate the DNA sequence gene of interest. (2) Insert your DNA of interest into the vector plasmid: (a) cut both vector DNA and gene of interest with the same restriction enzymes, (b) mix the DNAs: they join by base pairing, (c) add DNA ligase to bond the pieces covalently. The result is a recombinant plasmid.

Detailed explanation-4: -Bacterial transformation is a process of horizontal gene transfer by which some bacteria take up foreign genetic material (naked DNA) from the environment.
