The sugar of RNA is much more reactive than the sugar of DNA. RNA is an acronym for ribonucleic acid, and it is a molecule made up of nucleotides, and it is found inside the cell structure. Each nucleotide in RNA is comprised of a nitrogen base, ribosomal sugar, and phosphate.
The nitrogenous RNAs include adenine, guanine, cytosine, and uracil, which replaces thymine in DNA. RNA is a complex combination of high molecular weight that functions in cellular protein synthesis and replaces DNA as a genetic code carrier in some viruses. It has numerous biological roles in coding and decoding, control and expression of genes.
Unlike DNA, RNA is constructed as a chain of nucleotides, but unlike DNA, RNA is found in nature as a single-strand folded onto itself, rather than a paired double-strand. It is mostly discovered within the nucleus of cells. DNA is present in all live beings and contains the genetic instructions necessary to develop and maintain life.
