  • Q1
    Which is the correct order of events in creating a transgenic organism?
    a plasmid is cut by a restriction enzyme - the plasmid is transferred to a bacterial cell - a specific gene is identified in DNA - the DNA fragment is placed in a plasmid - the DNA fragment of interest is isolated
    a specific gene is identified in DNA - the DNA fragment of interest is isolated - a plasmid is cut by a restriction enzyme - the DNA fragment is placed in a plasmid - the plasmid is transferred to a bacterial cell
    the DNA fragment of interest is isolated - the plasmid is transferred to a bacterial cell - a specific gene is identified in DNA - the DNA fragment is placed in a plasmid - a plasmid is cut by a restriction enzyme
    the DNA fragment is placed in a plasmid - the DNA fragment of interest is isolated - a specific gene is identified in DNA - the plasmid is transferred to a bacterial cell - a plasmid is cut by a restriction enzyme
