Want this question answered?
rough endoplasmic reticulum is located on the nuclear envelope.
In cytoplasm,On Rough ER,in mitochondria and chloroplasts
it is cytoplasm
The mitochondria of a cell are located in the cytoplasm.
Ribosomes
The rough ER is located (borders) the nucleus.
They are in cytoplasm. In eukaryotes some are embedded in rough ER
ribosomes
If your question is "What is the site of the protein synthesis that occurs in the cytoplasm and on the rough ER?" then the answer is as follows: Protein synthesis occurs in both cases at the ribosomes, which are protein and RNA structures that catalyse the steps of protein synthesis. There are ribosomes free in the cytoplasm and attached to the rough ER. The proteins are processed in the cytoplasm or the ER after synthesis, this involves processes such as folding. The finished proteins are found free in the cytoplasm if they are synthesised by cytoplasmic ribosomes. If they are synthesised on the ER they are transported across the ER membrane into the lumen of the ER and stored in vesicles or released into the interstitial space via secretory vesicles.
The rough endoplasmic reticulum is a system of interconnected sacs located in the plant cell's cytoplasm. It transports materials through the cell and produces proteins in structures called cisternae.
No . cytoplasm also contain rrna .
They are free in cytoplasm. Many attached to the rough ER
