12 Questions
What is the main goal of gene cloning in the context of DNA manipulation?
To make thousands of copies of a single gene of interest
In the process of gene design, what do genetic engineers typically do to a cloned gene in order to make it functional in a new organism?
Replace gene regions with enzymes
Which method of transformation aims to insert new genes into cells without harming them?
Agrobacterium
What is the purpose of backcross breeding in agriculture when dealing with transgenic plants?
To obtain high yielding transgenic lines by crossing with elite breeding lines
What distinguishes recombinant DNA from normal DNA?
It is artificially created by combining DNA from different sources
How does gene design differ from gene cloning in the context of genetic engineering processes?
Gene cloning creates multiple gene copies, while gene design modifies the genes for functionality
