Suppose that you could synthesize an mRNA with a random sequence of nucleotides but attach the information for a normal signal sequence to one end, and that you could mark the molecule so you can observe what happens to it after you introduce it to the interior of a cell. Choose the most logical prediction.
O It would not enter the ER, because the signal sequence only works for the insulin protein.
O The signal sequence would bind to the RNA-protein particle and the protein would enter the ER.
O It would not enter the ER, because the MRNA sequence is random and not meaningful in terms of the cell's fitness.
