After cutting pglo with one of these three enzymes (ecori, psti or bamhi), a researcher then removed all the dna fragment(s) that are less than 2000 bp from the restriction digest. next, she ligated the remaining linear dna fragment back together to make a plasmid (that is now missing some dna compared to the original plasmid). finally, she transformed bacteria with this plasmid, and her transformation results indicated that the transformed bacteria were no longer ampicillin-resistant. which enzyme did she cut with? explain your answer.
