  • Harden and Young also demonstrated that the process stops before all sugar (glucose) has been used up, but it starts again on addition of inorganic phosphate, and they suggested that hexose phosphates are formed in the early steps of fermentation. von Euler had done important work on the structure of co-zymase, shown to be nicotinamide adenine dinucleotide (NAD, earlier called DPN).

  • Also if the repeat's flanking sequences are strongly conserved (about 10% of dinucleotide repeats have flanking sequences conserved throughout mammals) those mRNAs nearly always encode proteins critical to central nervous system development.

  • However, for example, dinucleotide simple repeats are frequently associated with membrane-targeted proteins.

  • In a database study of all reported dinucleotide repeats in UTRs, the repeats were 9 times more likely to appear in mRNAs encoding membrane proteins than other activities.

  • Blanchard assigned one color to four dinucleotide combinations.

    The $1,000 Genome

  • In laboratory experiments on human cells, investigators found that cutting calories, while preserving the nutrients they need, starts a chain reaction in the mitochondria — or power houses of the cell — that results in the build-up of a coenzyme called NAD (Nicotinamide adenine dinucleotide).

  • ADH = alcohol dehydrogenase, a specific catalyzing enzyme NAD = nicotinamide adenine dinucleotide, a common cellular reducing agent


  • A new class of genetic markers, microsatellite repeats, was identified in 1989 (Litt and Luty 1989; Tautz 1989; Weber and May 1989); because these sets of tandem repeats of short (either dinucleotide, trinucleotide, or tetranucleotide) DNA sequences are more highly polymorphic and detectable by PCR, microsatellites quickly replaced RFLPs as markers of choice for genetic linkage mapping and furnished the STS markers which facilitated the integration of genetic and physical maps.

    The Human Genome Project

  • He worked on production of Adenosine tri phosphate (ATP), the multifunctional nucleotide involved in intracellular energy transfer, from Nicotinamide adenine dinucleotide (NAD), and Nicotinamide adenine dinucleotide phosphate (NADP) which plays key role as a carrier of electron and participate in redox reaction.

    Prof. Arthur Kornberg, Nobel laureate, died on Sunday, October 26, 2007

  • In addition to producing lactic acid, lactobacilli also have the ability to produce hydrogen peroxide through oxidation of reduced nicotinamide adenine dinucleotide (NADH) by flavin nucleotide, which reacts rapidly with gaseous oxygen.
