“A nucleotide is a combination of a ribose or deoxyribose sugar, a purine or pyrimidine base, and a phosphate group.”
“The basic structure of a nucleotide contains ribose with a nitrogenous base and a phosphate group.”
“Another difference between DNA and RNA is that RNA contains ribose, rather than deoxyribose.”
riboflavin
(biochemistry) Yellow or orange-yellow water-solublecompound, a member of the vitamin Bcomplex, that acts as a growth-promoting factor in humans and other animals.
“The overall sequence that leads to the parent purine ribonucleotide, which is inosinic acid, involves 10 enzymatic steps.”
“Phase 1 clinical trials provide evidence that the nanorobots can silence a gene that makes an essential enzyme called ribonucleotide reductase.”
“A monoclonal antibody which is specifically reactive with a human ribonnucleotide reductase R2 subunit and which is capable of inhibiting ribonucleotide reductase activity.”
“These siRNAs are incorporated into a ribonucleoprotein complex known as the RNA-induced silencing complex, which targets homologous transcripts, catalyzing their degradation.”
“Plasmodesmata are unique to plants and form an intercellular continuum for the transport of solutes, signals, and ribonucleoprotein complexes.”
ribosyl
(organic chemistry) any univalent radical derived from ribose
