Match the type of RNA to its main function

1) mRNA: carries messages from the nucleus

2) tRNA: brings amino acids to ribosomes

3) rRNA: helps make up ribosomes

Final answer:

The three main types of RNA involved in protein synthesis are mRNA, which carries instructions from DNA; tRNA, which brings amino acids to ribosomes; and rRNA, which helps form the ribosomes where proteins are assembled.

Explanation:

The three main types of RNA each have a unique and critical role in the process of protein synthesis. Messenger RNA (mRNA) is responsible for carrying the genetic instructions from the DNA in the nucleus to the cytoplasm, where these instructions direct protein synthesis. Transfer RNA (tRNA) has the job of bringing amino acids to the ribosome, a process vital for the construction of proteins. Finally, Ribosomal RNA (rRNA) helps form the ribosomes themselves, structures that serve as the site where proteins are assembled according to the blueprint provided by mRNA.

mRNA is read in sets of three bases known as codons, with each codon specifying a single amino acid. rRNA ensures the proper alignment of the mRNA and the ribosomes, and has enzymatic activity which catalyzes the formation of peptide bonds between aligned amino acids. Meanwhile, tRNA brings the correct amino acids to the ribosome, facilitating the creation of the polypeptide chain that will fold into a functional protein.
