An antibiotic enters bacterial cells through a membrane channel protein, P.
Some bacterial cells have shown resistance to this antibiotic by acquiring a mutation which alters P. This mutation prevents the entry of the antibiotic into the cell.
Which conclusions can be drawn about how resistance to this antibiotic developed in these bacteria?
1 The mutation changed the order of the amino acids in the gene coding for P.
2 The mutation resulted in the production of P with an altered tertiary structure.
3 The antibiotic is a hydrophobic molecule and so cannot cross the phospholipid bilayer to enter the cell.
