 The full form of RNA is Ribo Nucleic Acid. Its full form doesn't change depending upon the cells. 
Another thing, RNA is a nucleic acid and consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate. RNA is very similar to DNA, but differs in a few important structural details: in the cell, RNA is usually single-stranded, while DNA is usually double-stranded; RNA nucleotides contain ribose while DNA contains deoxyribose (a type of ribose that lacks one oxygen atom); and RNA has the base uracil rather than thymine that is present in DNA. 
RNA is transcribed from DNA by enzymes called RNA polymerases and is generally further processed by other enzymes. RNA is central to the synthesis of proteins. Here, a type of RNA called messenger RNA carries information from DNA to structures called ribosomes. These ribosomes are made from proteins and ribosomal RNAs, which come together to form a molecular machine that can read messenger RNAs and translate the information they carry into proteins. There are RNAs with other roles – in particular regulating which genes are expressed, but also as the genome of most viruses.

RNA-- RIBO NUCLEIC ACID.THIS IS AN IMPORTANT MOLECULE WHICH CONTAINS LONG CHAINS OF NUCLEOTIDES.DNS AND RNA ARE DIFFERENT. SUGAR IS THE MAIN DIFFERENCE IN THEM. DNA CONTAINS  DEXYRIBOSE MOLECULE WHICH CONTAINS SUGAR BUT RNA CONTAINS RIBOSE MOLECULE.


HOPE THIS HELPS U.
