Virus Assembly G06.920.925.950
Pheromones D010675 [Allelochemicals in that the elicited response of the receiver is adaptively favorable to the emitter but not to the receiver. They are sometimes called repellents (INSECT REPELLENTS) or deterrents. , Allelochemicals in that the elicited response of the receiver is adaptively favorable to the receiver but not to the emitter. They are sometimes called attractants. , Chemical substances, excreted by an organism into the environment, that elicit behavioral or physiological responses from organisms of a different species . Perception of these chemical signals may be olfactory or by contact. Allelochemicals are subdivided into several groups depending on the response of the receiver and its adaptive effect to the emitter. They can be allomones, kairomones, or synomones. , Allelochemicals in that the elicited response of the receiver is adaptively favorable to both emitter and receiver. , Chemical substances, excreted by an organism into the environment, that elicit behavioral or physiological responses from other organisms of the same species. Perception of these chemical signals may be olfactory or by contact. ]
Tuberous Sclerosis C04.651.800
Neoplasms, Multiple Primary C04.651
Nucleolus Organizer Region D009697 [The chromosome region which is active in nucleolus formation and which functions in the synthesis of ribosomal RNA. ]
Phialophora D010676 [A mitosporic fungal genus. Phialophora verrucosa is a cause of chromomycosis (CHROMOBLASTOMYCOSIS). Ophiobolus is the teleomorph of Phialophora. ]
Nucleic Acid Precursors D009694 [Use for nucleic acid precursors in general or for which there is no specific heading. ]
Philadelphia Chromosome D010677 [An aberrant form of human CHROMOSOME 22 characterized by translocation of the distal end of chromosome 9 from 9q34, to the long arm of chromosome 22 at 22q11. It is present in the bone marrow cells of 80 to 90 per cent of patients with chronic myelocytic leukemia (LEUKEMIA, MYELOGENOUS, CHRONIC, BCR-ABL POSITIVE). ]
Nucleic Acid Renaturation D009695 [The reformation of all, or part of, the native conformation of a nucleic acid molecule after the molecule has undergone denaturation. ]
Philately D010678 [Study of stamps or postal markings. It usually refers to the design and commemorative aspects of the stamp. ]
Epimedium B01.650.940.800.575.912.250.125.342
Nucleic Acid Heteroduplexes D009692 [Double-stranded nucleic acid molecules (DNA-DNA or DNA-RNA) which contain regions of nucleotide mismatches (non-complementary). In vivo, these heteroduplexes can result from mutation or genetic recombination; in vitro, they are formed by nucleic acid hybridization. Electron microscopic analysis of the resulting heteroduplexes facilitates the mapping of regions of base sequence homology of nucleic acids. ]
Philippines D010679 [A country in southeastern Asia, archipelago between the Philippine Sea and the South China Sea, and east of Vietnam. The capital is Manila. ]
Nucleic Acid Hybridization D009693 [Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands. (Kendrew, Encyclopedia of Molecular Biology, 1994, p503) ]
Endothelium-Dependent Relaxing Factors D27.505.954.411.918.500
Vasodilator Agents D27.505.954.411.918
Nucleic Acid Conformation D009690 [The spatial arrangement of the atoms of a nucleic acid or polynucleotide that results in its characteristic 3-dimensional shape. ]
Nucleic Acid Denaturation D009691 [Disruption of the secondary structure of nucleic acids by heat, extreme pH or chemical treatment. Double strand DNA is "melted" by dissociation of the non-covalent hydrogen bonds and hydrophobic interactions. Denatured DNA appears to be a single-stranded flexible structure. The effects of denaturation on RNA are similar though less pronounced and largely reversible. ]
Drug Resistance, Neoplasm D019008 [Resistance or diminished response of a neoplasm to an antineoplastic agent in humans, animals, or cell or tissue cultures. ]
