B) lysosome
C) nucleolus
D) nucleus
E) rough endoplasmic reticulum

Question

Quizplus · Accepted Answer

The organelle surrounded by a double membrane that carries the coding for protein synthesis is the nucleus. The nucleolus, within the nucleus, is responsible for the assembly of ribosomes, which are involved in protein synthesis. The smooth and rough endoplasmic reticulum are involved in protein synthesis and modification, but do not carry the genetic information. Lysosomes are responsible for breaking down cellular waste and do not play a role in protein synthesis.
