A protein that is normally localized in the cytoplasm has been engineered so that it will be secreted from the cell instead.
Which of the following represents the most likely pathway for the protein after it has been completely synthesized?

A. sER \to Golgi \to secretory vesicle \to environment
B. rER \to secretory vesicle \to Golgi \to environment
C. rER \to Golgi \to sER \to cytoplasm \to environment
D. cytoplasm \to rER \to Golgi \to secretory vesicle \to environment
E. rER \to Golgi \to secretory vesicle \to environment

E. rER \to Golgi \to secretory vesicle \to environment

Explanation:

A protein that is normally localized in the cytoplasm has been engineered so that it will be secreted from the cell instead will follow the following sequence:

Rough endoplasmic reticulum (RER) (where the protien is being snthesized)> Golgi apparatus (where the sorting and packaging of the protien occurs)> Secretory vesicles> Environment.

Hence E. rER \to Golgi \to secretory vesicle \to environment is the right answer.

i think the answer is b.

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides
