Here's why:
* Instructions: Ribosomes receive instructions from messenger RNA (mRNA), which carries the genetic code from DNA.
* Building Blocks: They use transfer RNA (tRNA) to bring in amino acids, the building blocks of proteins.
* Assembly Line: Ribosomes act as an assembly line, linking amino acids together in the order specified by the mRNA, creating a polypeptide chain.
* Folding: The polypeptide chain then folds into a specific three-dimensional shape, forming the functional protein.
In short, ribosomes are the cellular machines that translate genetic code into functional proteins.
