Several procedures involved in the creation of a transgenic organism are listed. 1. A specific gene is identified in DNA. 2. The DNA fragment is placed in a plasmid. 3. The DNA fragment of interest is isolated. 4. The plasmid is transferred to a bacterial cell. 5. A plasmid is cut by a restriction enzyme. Which selection represents the correct order of events in creating a transgenic organism?

Explanation:
Detailed explanation-1: -The three principal methods used for the creation of transgenic animals are DNA microinjection, embryonic stem cell-mediated gene transfer and retrovirus-mediated gene transfer.
Detailed explanation-2: -Genetic engineering is accomplished in three basic steps. These are (1) The isolation of DNA fragments from a donor organism; (2) The insertion of an isolated donor DNA fragment into a vector genome and (3) The growth of a recombinant vector in an appropriate host.
Detailed explanation-3: -The key steps involved in genetic engineering are identifying a trait of interest, isolating that trait, inserting that trait into a desired organism, and then propagating that organism.
