![]() ![]() It can also be found in the ribosomes as ribosomal RNA (rRNA). It sits inside the nucleus as messenger RNA (mRNA) and in the cell cytoplasm as transfer RNA (tRNA). RNA is found in several locations in the cell. Ribosomal RNA is involved in building the protein in a ribosome. Transfer RNA is involved in decoding this information. Messenger RNA shuttles the information out of the nucleus. ![]() It is a very complex process and there are several different types of RNA involved. This is translated in the ribosomes to produce a protein. It carries out its role by transcribing the genetic instructions inside the nucleus by producing a complementary strand of RNA. So what is the function of RNA? It is an intermediary between DNA, which houses the instructions to make a protein, and the ribosomes, which are a cell’s protein making factory. Nucleic - Refers to the fact that it originates in the nucleus. Contrast this with the sugar group in DNA which is dexoyribose. Ribo - This is short for ribose and it is a pentose sugar. Both DNA and RNA have four nitrogenous bases Adenine, Cytosine, Guanine, but instead of Thymine, RNA has a different base, called Uracil.īefore we go any further, what does RNA actually stand for? Whilst DNA consists of two long twisted strands, sometimes called the double helix, RNA exists as one strand. Genes are made up of DNA, which is a set of instructions for how cells grow and develop. Though similar to DNA, in that it is a nucleic acid, there are some stark differences. DNA definition, deoxyribonucleic acid: an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms, constructed of two nucleotide strands coiled around each other in a ladderlike arrangement with the sidepieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine. GMO stands for Genetically Modified Organism. Yet the function of RNA is just as important for the manufacture of proteins. But whilst DNA basks in the spotlight and gets all the attention, RNA is less well known. ![]()
