Explanation:

RNA stands for Ribo Nucleic Acid. It is composed of 3 parts. Ribose sugar (5-membered Aldose sugar), Nitrogenous base (AUGC), and a phosphate group. RNA is a polymer of many subunits linked together, which are known as nucleotides. RNA and DNA are actually very similar, and the main differenc between them is in the Ribose sugar. DNA actually means 2'-DeoxyriboNucleic Acid, so the components of DNA are actually a sugar modification of RNA

RNA is generally divided up in the cell into 3 main parts. Ribosomal RNA (rRNA), which is responsible for making proteins.....transferRNA (tRNA), which is responsible for helping to make proteins...and messenger RNA (mRNA), which is an RNA copy of a DNA gene.

In all cases, the RNA component of these different types are all the same - their difference comes from their function in the cell.
