What is de novo in microbiology?

De novo mutation: a phrase in genetics that means a form of a genetic mutation that occurs for the first time in a family member. The mutation (e.g. deletion) could lead to variants inside a germ cell of one of the parents. The variant could also come from a mutated gene inside the fertilized egg.

What is meant by de novo gene?

De novo gene birth is the process by which new genes evolve from DNA sequences that were ancestrally non-genic. De novo genes represent a subset of novel genes, and may be protein-coding or instead act as RNA genes [1].

What is de novo genome assembly?

De novo genome assembly is a strategy for genome assembly, representing the genome assembly of a novel genome from scratch without the aid of reference genomic data. De novo genome assemblies assume no prior knowledge of the source DNA sequence length, layout or composition.

What does de novo mean in clinical trials?

The De Novo request provides a marketing pathway to classify novel medical devices for which general controls alone, or general and special controls, provide reasonable assurance of safety and effectiveness for the intended use, but for which there is no legally marketed predicate device.

What is a de novo pathway?

noun, plural: de novo pathways. (biochemistry) A biochemical pathway where a complex biomolecule is synthesized anew from simple precursor molecules. Supplement. An example is the synthesis of complex biomolecules from simple units, e.g. of protein from amino acids.

What is de novo DNA sequencing?

De novo sequencing refers to sequencing a novel genome where there is no reference sequence available for alignment. Sequence reads are assembled as contigs, and the coverage quality of de novo sequence data depends on the size and continuity of the contigs (ie, the number of gaps in the data).

What is de novo RNA synthesis?

De novo synthesis is a unique phase in the transcription cycle where the RNA polymerase binds two nucleotides rather than a nascent RNA polymer and a single nucleotide. For bacteriophage T7 RNA polymerase, transcription begins with a marked preference for GTP at the +1 and +2 positions.

What is another word for de novo?

anew; afresh
anew; afresh; again; from the beginning.

What is Denovo and salvage pathway?

De novo pathway is a pathway of newly synthesizing complex compounds from small molecules. Salvage pathway is a pathway of utilizing previously made compounds in order to synthesize complex compounds. In nucleotide synthesis, both de novo and salvage pathways are seen.
