Ribosomes work by connecting amino acids (up to a rate of up to 200 per minute) in the order specified by the mRNA molecules, which in turn transcribe the information contained in the DNA. A large protein may take 2-3 hours to translate. When an amino acid chain has been fully translated, it is expelled in the cytoplasm of the cell and folded into a functional protein.
Explanation:
A ribosome is a complex macromolecular structure in the cell that is involved in the course of translation. This is an important function of all living cells, taking into account protein production.
There are two subunits that comprise the ribosome: the large and small subunits. The small subunit reads the mRNA, while the large subunit connects the amino acids (they are carried to the ribosome by the tRNA) in a polypeptide chain.
<span>Ribosomes are where the proteins are put together. It is where they are transcribed. Once the ribosomes synthesizing these proteins become bound to the rough ER, the proteins enter or cross the ER membrane cotranslationally — that is, during their synthesis. Soluble proteins in this class first are localized in the ER lumen and subsequently are sorted to the lumen of other organelles or are secreted from the cell. Likewise, the integral membrane proteins in this class initially are inserted into the rough ER membrane during their synthesis; some remain there, but many eventually become localized to the plasma membrane or membranes of the smooth ER, Golgi complex, lysosomes, or endosomes.
Woof! I hope that helps you! That was a rough question! x3 xo Leafling</span>
