Definition: A group of physical features on a chromosome that act together in such a way to eventually (via transcription and perhaps translation) result in a gene product.
Definition: An artificially constructed gene (or genes) that is inserted into the germline in a manner that ensures its function, replication and tranmission as a normal gene. top
Definition: One of a number of different forms of a gene that occur at the same locus but differ in base sequence.
Definition: The basic subunit of any living thing, typically containing genetic material, an energy-producing system, and other components, all surrounded by a wall and/or membrane. A cell group is a collection of cells that show very similar, if not identical phenotypic characteristics.
Example: sensory neuron, muscle, AB.p
Definition: Subcellular structures, locations, and macromolecular complexes.
Examples: SnoRNA, mitochondrion, nucleus, telomere, and origin recognition complex.
Definition: Nucleotides that are the subunits of DNA and RNA..

Definition: A virus or a unicellular or multicellular prokaryote or eukaryote.
Example: C. elegans, Homo sapiens, S. pombe
Definition: A feature or component of a biological entity.
Example: Transposon, Codon, Valine
Definition: The functional, morphological or time stages through which an organism passes.
Definition: A set of observable physical characteristics of an individual organism.
Example: Fog, Dumpy, Phenotype, Wildtype
Definition: An intraspecific group of organisms that possess only one or a few distinctive traits and are maintained as an artificial breeding group.
Definition: The state of condition of an organism which comes to expression in the production of germ cells.
Definition: Any chemical substance that affects the functioning of living things directly or indirectly.
Definition: The tasks performed by individual gene products.
1st example: Transcription factor
2nd example: DNA helicase
Definition: Indicates that something is produced by or follows a mutation; also a mutant gene.
1st example: ced-1 mutant background.
2nd example: Deformed tail region.
Definition: A vector used for cloning DNA.
Examples: Cosmid, cDNA, YAC, yk1215d07
Definition: A spatial connectivity supported by noncovalent bonds.
Example: The PHA-4 protein binds to a regulatory region of the pharynx myosin-encoding myo-2 gene.
Definition: An abstract connectivity established by an abstract concept or unspecified process or function.
1st example: Another partner for sdc-2 is sdc-3.
2nd example: Dpy genes and sdc genes work together in all aspects of dosage compensation.
Definition: The power to bring about a result upon an entity.
1st example: We examined tkr-1 and tkr-2 transgenics for effects on stress resistance and longevity.
2nd example: Therefore , the possibility existed that RNAi of pdk-1 actually abolishes pdk-1 gene activity.
Definition: Indication that a thing or part is specially fitted or used as or for which a thing exists.
Example: UNC-45 is a component of thick filaments and functions as a stabilizer for MHC B.
Definition: A (hierarchical) sequence, network, or part of it, of reactions or processes that involve biological entities.
Example: Therefore, the genes acting downstream of gsk-3 in the Wnt pathway are not required for proper EMS spindle orientation.
Definition: The act of fixing or adjusting a quality (time, amount, degree, or rate) of an entity upon itself (autoregulation) or on another entity or entities (A regulates B).
1st example: Third , son-1 ( sy549 ) enhances the phenotypes of a weak allele of lin-17 to null-like phenotypes.
2nd example: Interestingly, pie-1 mutants inappropriately derepress the transcription of several genes in germline blastomeres.
Definition: An examination of two or more items to establish similarities and dissimilarities.
1st example: Unc-129 mutants on their own exhibit defects in dorsalward axonal projection that resemble those caused by unc-6 or unc-5 mutations.
2nd example: The general gene organization is similar to that of Drosophila and vertebrates but the gene expression mechanism was somewhat different.
Definition: An aspect or quality (as resemblance) that connects two or more things or parts in space.
1st example: However, unc-25 and unc-47 are 0.15 map units apart .
2nd example: Reporter gene transformation studies demonstrated that regulation of this gene is mediated by a compact region close to the transcription start site.
Definition: An aspect or quality (as resemblance) that connects two or more things or parts in time.
Example: The factors that regulate these genes will be expressed in the same cell lineage but earlier than the expression of target genes.
Definition: To be present in an event or process as an active element or member.
1st example: mec-7 is a b-tubulin gene required for the production of 15-protofilament microtubules in Caenorhabditis elegans.
2nd example: Two predicted transcription factors, skn-1 and pop-1, are necessary for the MS developmental program, including the production of pharyngeal cells.
3rd example: This mutual exclusivity of cell fates presumably involves a network of gene activity that not only activates genes appropriate to that cell type but represses all others, thereby ensuring an either-or decision.
4th example: Pop-1 is involved in Wnt-dependent asymmetric cell division of the EMS blastomere.
Definition: The description of the character or quality of something.
1st example: Similarly, the ges-1 gene promoter contains a pair of GATA motifs that are required for proper intestine-specific expression.
2nd example: The gene has nine small introns typical of C elegans.
Definition: A position or site occupied or available for occupancy or marked by some distinguishing feature in time or space.
1st example: We ablated all cells in the gonad primordium of let-23 ( sa62 ) unc-4 ( e120 ) mnC1 or let-23 ( sa62 ) unc-4 ( e120 ) let-23 ( sa62 ) unc-4 ( e120 ) larvae before the first division of the somatic gonad precursors Z1 and Z4.
2nd example: We picked let-23 ( sa62 ) unc-4 ( e120 ) animals or unc-4 control animals at the L4 stage .
3rd example: The ced-4 ( n1162 ) allele contains an ochre stop mutation at codon 79 and is probably a molecular and genetic null allele.
Definition: A way, technique, or process for doing something.
Example: Cell ablation, Immunoprecipitation
N) Biological Process (Attribute Source: (Go, Textpresso); Attribute Type: (molecular, cellular, organismal, general); Attribute Biosynthesis: (transcription, translation, expression, replication, other, no)) top
Definition: Broad biological goals, such as mitosis or purine metabolism, that are accomplished by ordered assemblies of molecular functions.
1st example: The expression of syn-4 in the seam cells of L1 larvae might indicate that syn-4 plays a role in secretion of the worm cuticle.
2nd example: All four fly msl genes are transcribed in both sexes.
Definition: The exertion of energy or influence on any entity.
1st example: sel-12 activity facilitates the activity of LIN-12 and GLP-1 , two receptors of the LIN-12yNotch family.
2nd example: This data supports the idea that gld-2(lf):: gld-1(lf) double mutants never enter meiosis.
3rd example: Neither the sma6(e1482) nor the sma-4(e805) alleles elicit tail defects.
Definition: A word or phrase that has the function of describing the state or condition of an entity.
1st example: Sterility is caused by necrotic death of germ cells during larval development.
