This genus shows an ample metabolic diversity and a wide range of biotechnological applications (Fonseca, Heinzle, Wittmann, & Gombert, 2008), such as the production of enzymes, ribonucleotides, oligosaccharides, oligopeptides, heterologous protein, aromatic compounds, ethanol and biomass for the food industry (Van Ooyen et al.
8] erythrocytes), and 6-methylmercaptopurine ribonucleotides (6-MMPRs) were very high (11 666 pmol/8 x [10.
Ribose which is associated with the ribonucleotides in the muscle is highly involved in flavour producing reactions during heating of meat (Mottram, 1998).
One example of these markers is the URA3 gene that encodes orotidine 5-monophosphate decarboxylase (OMPD Case), an enzyme involved in the de novo synthesis of pyrimidine ribonucleotides (10).
The p53 protein is highly sensitive and able to detect any mutations in the sequence of the genetic code arising from a range of factors, capturing, among other stimuli, errors in DNA replication, inadequate induction of an oncogene, injury due to ionizing radiation, action of viruses, depletion of ribonucleotides, telomerase erosion, hypoxia and anoxia as shown in figure 3 (VOUSDEN & LU, 2002).
Each kit comes with enough pieces to make 12 glucose monomers, 12 amino acids, 12 deoxyribonucleotides, 12 ribonucleotides, 12 triglycerides, or 12 phospholipids.
Other proteins link these nucleotides into DNA or RNA sequences, depending on their type (deoxyribonucleotides into DNA, and ribonucleotides into RNA).

At the University of Manchester in England, chemist John Sutherland and his team reported discovering a natural set of reactions by which ribonucleotides, the fundamental units of RNA, could have built up on the young, lifeless Earth.
The subnetworks are (1) the core metabolism going from the molecules of the five starting points of autotrophic anabolism to the 20 coded amino acids and 4 ribonucleotides that would have existed in the RNA world, (2) the pathways leading from core metabolism to the standard cofactors or coenzymes of extant biochemistry, (3) the pathways from acetate to the polar lipids that become the cell membrane components, (4) the isoprenoid pathways leading to ubiquinone and hopanoids, and (5) the peptido-glygan synthesis pathways.
Scientists from Scandinavia and the US examine the enzymes responsible for the conversion of ribonucleotides to deoxyribunucleotides, the four types of which are required for the synthesis and repair of DNA in all living cells.
