Here's why:
* Ribosomes are the protein factories of the cell. They read the genetic code from messenger RNA (mRNA) and use that information to link amino acids together, forming polypeptide chains.
* Polypeptide chains are the building blocks of proteins. They fold into specific three-dimensional structures, giving each protein its unique function.
While other cellular components play roles in protein production, like the nucleus where DNA is stored and the endoplasmic reticulum (ER) where proteins are further processed and folded, the ribosomes are the primary site of protein synthesis.
