Detailed explanation-1: -Which of the following statements about recombinant DNA technology is FALSE? It has limited application because genes of interest cannot be moved from one type of cell to another. This statement is FALSE. Recombinant DNA technology is commonly used to move DNA from one type of cell to another.
Detailed explanation-2: -…in recombinant DNA technology is amplification. This is carried out by inserting the recombinant DNA molecule into a bacterial cell, which replicates and produces many copies of the bacterial genome and the recombinant DNA molecule (constituting a DNA clone).
Detailed explanation-3: -Recombinant DNA technology makes it possible to change the genetic composition of living organisms. Recombinant DNA uses the genes from one organism and combines it with the genes of another organism. This means that the genes have already been altered.
Detailed explanation-4: -Definition. A vector, as related to molecular biology, is a DNA molecule (often plasmid or virus) that is used as a vehicle to carry a particular DNA segment into a host cell as part of a cloning or recombinant DNA technique.
