Proteins That are Mainly Used Inside the Cell are Synthesized

Question

Proteins that are mainly used inside the cell are synthesized
A)in the nucleus.
B)on polyribosomes.
C)on rough ER.
D)in the nucleoli.

Accepted Answer

Proteins that are mainly used inside the cell are synthesized on polyribosomes, which are located in the cytoplasm. The other options (A, C, D) are all involved in protein synthesis, but they are not specific to proteins that are mainly used inside the cell. The nucleus is responsible for DNA replication and transcription, the rough ER is involved in the synthesis and modification of secretory and membrane proteins, and the nucleoli are involved in the synthesis of ribosomal RNA.
