Which of the following statements explains how N-formylmethionine (fMet) is only associated with the 5' AUG initiation codon and not with internal AUG codons, given that methionine in both cases in encoded by an AUG in the mRNA. Select all that apply. Group of answer choices Only fMet-tRNA(fMet) can bind first to the P site in the ribosome. There are more than one tRNA with the 5' CAU 3' anticodon. fMet is always incorporated at interior AUG sites and then deformylated after translation. The N-formyl group attached to methionine prevents fMet from entering interior positions in a polypeptide.

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
