In order for a milk protein to be secreted,its mRNA if first encoded into proteins on ribosomes

Question

Quizplus · Accepted Answer

Milk proteins are synthesized on ribosomes that are attached to the rough endoplasmic reticulum (ER), where they undergo post-translational modifications and are packaged into vesicles for secretion. The rough ER is responsible for protein synthesis and modification, while the smooth ER is involved in lipid synthesis and detoxification. Therefore, choices A, C, and E can be eliminated. Similarly, mRNA is transcribed in the nucleus, but it is transported out of the nucleus for translation by ribosomes in the cytoplasm. Therefore, choice B can also be eliminated.
