In biochemistry, a ribonucleotide is a nucleotide containing ribose as its pentose component. It is considered a molecular precursor of nucleic acids. Nucleotides are the basic building blocks of DNA and RNA. Ribonucleotides themselves are basic monomeric building blocks for RNA. Deoxyribonucleotides, … See more General structure The general structure of a ribonucleotide consists of a phosphate group, a ribose sugar group, and a nucleobase, in which the nucleobase can either be adenine, guanine, cytosine, … See more Precursors of deoxyribonucleotides Scientists believe that RNA was developed before DNA. The reduction of ribonucleotides to deoxyribonucleotides … See more In order to understand how life arose, knowledge is required of the chemical pathways that permit formation of the key building blocks of … See more • Ribonucleosides or ribosides See more Ribonucleotide synthesis Ribonucleotides can be synthesized in organisms from smaller molecules through the de novo pathway or recycled through the salvage pathway. In the case of the de novo pathway, both purines and pyrimidines are … See more Prior to James Watson and Francis Crick's landmark paper that detailed the structure of DNA from Rosalind Franklin's X-ray crystallography image, … See more WebAug 23, 2024 · 11.3: Deoxyribonucleotide de novo Biosynthesis. Synthesis of deoxyribonucleotides de novo requires an interesting enzyme called ribonucleotide reductase (RNR). RNR catalyzes the formation of deoxyribonucleotides from ribonucleotides. The most common form of RNR is the Type I enzyme, whose …
