De novo: Literally, 'from new' as opposed to inherited.
Degeneracy: A feature of the genetic code. More than one nucleotide triplet can code for the same amino acid.
De novo pathway A biosynthetic pathway that builds the final product from simple precursors. See also salvage pathway.
Decarboxylase An enzyme that removes a carbon atom from a substrate in the form of carbon dioxide.
[edit] De novo production
Some metabolic pathways that synthesize and consume NAD+ in vertebrates. The abbreviations are defined in the text.
Some sense of the probe resource requirements for de novo sequencing can be understood by the following "reverse" strategy applied to an array of Format 2 type.
Higher-throughput proteomic techniques are based on mass spectrometry, commonly peptide mass fingerprinting on simpler instruments, or de novo sequencing on instruments capable of more than one round of mass spectrometry.
Any such de novo synthesis of organic molecules is no longer possible. The molecules would be eaten by an existing organism or oxidized by the oxygen-rich atmosphere.
Progeny viruses are formed by de novo assembly from the newly synthesized components within the host cell. Transmission of the progeny viruses occurs by release from the host cell, and infection of new host cells.
(This contrasts with preformationism, which holds that the organism is already present in the gamete(s), merely growing and unfolding during development.) For example, organs are formed de novo in the embryo rather than increasing in size from ...
Batten's final criticism runs: "With a particular GA, we need to ask how much of the 'information' generated by the program is actually specified in the program, rather than being generated de novo.
