rRNA (ribosomal RNA)

Ribosomal RNA (rRNA) is a type of RNA that plays a crucial role in the process of protein synthesis within cells. It forms the main structural and functional components of ribosomes, the cellular machines that translate genetic information into proteins. rRNA helps to assemble amino acids in the correct order, based on the instructions from messenger RNA (mRNA). This process is essential for cell function and growth, as proteins are vital for many biological processes. In essence, rRNA acts as a foundation for ribosomes, enabling them to perform their role in building proteins.
