18 Questions
Which of the following is a key feature of genetic engineering?
Manipulation of a specific target gene
In genetic engineering, what is used to carry the desired gene into the target organism?
Plasmid or vector
Which technique can be used to enhance the expression of a desired gene?
Disrupting the inhibition of the gene's expression
What is the primary difference between genetic engineering and classical breeding?
Genetic engineering manipulates a specific gene, while classical breeding affects thousands of genes.
Which of the following is an advantage of genetic engineering over classical breeding?
Genetic engineering can introduce new traits that are not present in the parent organisms.
Which of the following is a key step in the genetic engineering process?
Isolating and manipulating a specific target gene
What term best describes the combination of DNA molecules from two different organisms?
Recombinant DNA

In genetic engineering, what is used to modify the traits of a target organism?
Plasmid
What does recombinant DNA technology involve?
Combining DNA from two different organisms
What is the primary function of a restriction enzyme in recombinant DNA technology?
To cleave DNA at specific recognition sequences
What is the role of a plasmid in recombinant DNA technology?
It serves as a vector for introducing foreign DNA into a host cell
Which of the following is NOT a fundamental difference between genetic engineering and traditional breeding?
Both genetic engineering and traditional breeding modify organisms genetically
What is the primary advantage of using recombinant DNA technology compared to traditional breeding methods?
It allows for the transfer of genes between different species
Which of the following is NOT a component required for successful recombinant DNA technology?
