Final answer:
Ribosomal RNA (rRNA) is the type of RNA that comprises the ribosomes, which are the sites of protein synthesis in a cell. Other types of RNA such as mRNA, tRNA, and miRNA play different roles in this process.
Step-by-step explanation:
The type of RNA that functions as the location where proteins are made is ribosomal RNA (rRNA). rRNA is a component of the ribosomes, which serve as the site for protein synthesis. The process begins with messenger RNA (mRNA), which carries the genetic code from DNA and conveys it to the ribosomes. In the ribosomes, rRNA interacts with mRNA and transfer RNA (tRNA) to facilitate the assembly of amino acids into proteins. It's important not to confuse rRNA with mRNA, tRNA, or microRNA (miRNA), as each has a distinct role in the overall process of protein synthesis. mRNA provides the coded instructions from the DNA, tRNA brings the appropriate amino acids to the growing protein chain, and miRNA regulates the use of mRNA for protein synthesis.
