what is the name of the sugar in the mrna nucleotides
Ribose is the sugar component of nucleotides. One of the main chemical differences between DNA and RNA is that in RNA, the sugar is ribose, but in DNA, the sugar is deoxy ribose, in which an oxygen has been removed. The connection that forms between nucleotides is between the sugar of the first nucleotide and the phosphate group of the second. 2  Each connection between nucleotides is a covalent bond, so the nucleic acids have a covalently attached sugar-phosphate backbone.
