Examine the results for group 4. Why would this group see growth without RFP in the third plate?
The bacteria cells did not transform.
The bacteria cells transformed, but did not incorporate the plasmid containing the RFP gene.
The bacteria cells transformed, but did not incorporate the plasmid with the arabinose gene.
Group 4 did not observe growth in the third plate.
