Hint: Ribonucleic acid (RNA) is a vital biological macromolecule found in all living cells. It is primarily involved in protein synthesis, carrying messenger instructions from DNA, which contains the genetic instructions necessary for life's growth and maintenance.

Complete answer:
The full form of RNA is ribonucleic acid. It is a compound of high molecular weight that functions in cellular protein synthesis. It also replaces DNA as a genetic carrier in some viruses.
RNA consists of a ribosome sugar; nucleotides attach two phosphodiester bonds forming different lengths. The nitrogenous bases are adenine, guanine, cytosine and uracil. uracil is replaced by thymine in DNA.

There are basically three Types of RNA. messenger RNA (mRNA), transfer RNA (tRNA) and ribosomal RNA (rRNA) which are present in all organisms. These and other types of RNA carry out biochemical reactions and also play an important role in normal cellular processes and diseases in protein synthesis.
• Messenger RNA carries genetic code from the DNA in the nucleus to ribosomes.
• Ribosomes are composed of RNA and protein. The ribosome protein is encoded by RNA. These are synthesized in nuclei that are fully assembled. rRNA physically moves along an mRNA molecule, catalysing the assembly of amino acids into protein chains.
• tRNA brings specific amino acids to the ribosome with their link to form protein.
So Ribosomal RNA is involved in the stitching together of amino acids to make a protein molecule

Note: RNA is principally involved in the synthesis of proteins, carrying the messenger instructions from DNA. In which it contains the genetic instructions required for the development and maintenance of life.
