I think it's called a hypothesis
Answer:
mRNA must start membrane protein in the cytoplasm and, after that, continue it in the rough ER.
Explanation:
Protein synthesis is initiated when mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes can be found in the r<em>ough endoplasmic reticulum</em> or floating in the cytosol. They read the mRNA code and add the correct amino acid using transference RNA to build the protein.
The <u>rough endoplasmic reticulum</u> is in charge of the synthesis and transport of the membrane proteins. It is also in charge of the latest protein modifications after transduction. Synthesis of membrane proteins <u>starts in the cytoplasm</u> with the production of a molecule portion known as a signal sequence. This portion leads the synthesizing protein and associated ribosome to a specific region in the Rough endoplasmic reticulum where it continues the protein building.
Membrane proteins are synthesized in the endoplasmic reticulum and <em>sent to the Golgi complex in vesicles</em>, where it happens the final association of carbohydrates with proteins. Finally, protein is transported <em>from the Golgi complex to its final destiny, the membrane. </em>
The immune system and the nervous system maintain extensive communication, including 'hardwiring' of sympathetic and parasympathetic nerves to lymphoid organs. Neurotransmitters such as acetylcholine, norepinephrine, vasoactive intestinal peptide, substance P and histamine modulate immune activity.
