RNA: RNA stands for Ribonucleic Acid . It is one of the principal organic macromolecules that is important for all known kinds of life. It performs diverse vital organic roles associated with protein synthesis along with transcription, decoding, law, and expression of genes. Structure of RNA It is a single-stranded molecule composed of ribonucleotides. Like DNA, It has three components: A Nitrogenous Base: It can be adenine (A), guanine (G), cytosine (C) or uracil (U). A Five-Carbon Sugar: It is ribose. A Phosphate Group: It is connected to the 3' function of one ribose and 5' role of the following ribose. The nucleotides of RNA are joined to one any other thru covalent bonds that exist between the phosphate of one molecule and the sugar of some...
