Answer :
The statement that a recombinant bacteria can be created by adding bacterial gene products from another strain of bacteria is False.
Recombinant bacteria are typically created through a process known in biology as genetic engineering or recombinant DNA technology. Here’s how this works step-by-step:
Identification and Isolation: The first step is to identify and isolate the specific gene of interest from one organism. This gene can be from a different strain of bacteria or even from a completely different organism.
Insertion into a Vector: The isolated gene is then inserted into a vector. A vector is a DNA molecule used as a vehicle to transfer genetic material to a target cell, and in bacteria, plasmids are commonly used vectors.
Transformation: The vector with the new gene is introduced into a bacterial cell. This process is known as transformation. The bacteria take up the vector DNA, incorporating the new gene into their own genetic material.
Expression and Cloning: The bacteria will then begin to express the new gene if conditions are right, producing the gene product, or protein, encoded by the new gene. Also, as the bacteria reproduce, they replicate the introduced gene, leading to a population of bacteria containing the recombinant DNA.
Simply adding bacterial gene products from another strain does not alter the genetic makeup of the bacteria – it is the DNA itself that must be altered through the aforementioned process. Therefore, the answer to the question is False.
