What's the difference between cognation and cognatus?
Cognation
Definition:
(n.) Relationship by blood; descent from the same original; kindred.
(n.) Participation of the same nature.
(n.) That tie of consanguinity which exists between persons descended from the same mother; -- used in distinction from agnation.
Example Sentences:
(1) The use of sigma 54 promoters, known to require cognate binding proteins, could allow the fine-tuning that provides the temporal ordering of flagellar gene transcription.
(2) To date, a cognate action of E2 on the GnRH pulse generator has not been described.
(3) Cognate sites in genomes that diverged approximately 100 million years ago can be detected by PCR assays based on primer pairs from unique sequences.
(4) Cognate heat shock proteins might be involved in this renaturation process.
(5) LEW rats immunized with each of the three DA MHC chains produced alloantibodies to these chains, suggesting that indirect allorecognition did occur, because of the requirement for cognate recognition of B cells by T helper cells.
(6) Microcultures of helper T (Th) cells and a few appropriately primed murine B cells can be used to detect cognate T-B interactions which lead to clonal production of IgM, IgG1, and IgE.
(7) We have investigated the structural relationship of heat-inducible and cognate members of the human hsp70 gene family.
(8) If protein mixtures are subjected to affinity elution the cognate pair [tRNAPhe-phenylalanyl-tRNA synthetase] is eluted first, followed by noncognate pairs.
(9) These results suggest that cognate T-B cell interactions may be important in the development of IgE immune responses in the normal host.
(10) Ribosomes programmed by different synonymous codons also differ in discriminating among near-cognate aminoacylated tRNAs.
(11) These results were then compared with CVB-specific IgM levels in the cognate patient sera.
(12) This line induces proliferation of and Ig secretion by I-Ak expressing but not H-2d resting and activated B cells as a result of cognate interactions.
(13) The protein has been designated as a stress cognate protein based on previous studies and data presented herein that this protein cross-reacted with a monoclonal antibody originally raised against the Drosophila 70 kilodalton heat shock protein.
(14) By radioactive in situ hybridization (ISH) using a fragment from the murine Pax-1 paired box that is almost identical to the respective sequences from the cognate human gene HuP48 and fluorescence in situ hybridization (FISH) using a complete mouse Pax-1 cDNA, we have assigned the human homologue of murine Pax-1, the PAX1 locus, to chromosome 20p.
(15) One region in most sigma factors makes sequence-specific contacts at the -10 region of its cognate promoters.
(16) This suggests that the SRE and its cognate protein are likely to be involved in the regulation of Krox-24 and presumably of other immediate-early serum response genes.
(17) A third Slp gene exists within this locus whose recombinant cognate did not express in L cells.
(18) Two of the hox appear to be cognates of the human Hu-1 (or mouse Hox 2.1) and the mouse Hox 1-3, while another is closely related to the mouse Hox 1-4.
(19) Comparison of our skeletal muscle translocator sequence with that of a recently published human fibroblast translocator cognate revealed that the two proteins are 88% identical and diverged about 275 million years ago.
(20) Comparison of the nucleotide and deduced amino acid sequence of this genome segment with cognate segments of isolates of BTV 1 from Australia and South Africa, and BTV 10 and BTV 17 from the United States, revealed homologies of 98%, 80%, 79%, and 79%, respectively, at the nucleotide level and 98%, 90%, 89%, and 90% identity, respectively, at the amino acid level.
Cognatus
Definition:
(n.) A person connected through cognation.
Example Sentences:
(1) Pigment granule migration in pigment cells and retinula cells of the digger wasp Sphex cognatus Smith was analysed morphologically after light adaptation to natural light, dark adaptation and after four selective chromatic adaptations in the range between 358 nm and 580 nm and used as the index of receptor cell sensitivity.
(2) The in vitro and in vivo responses of integumental chromatophores to alpha-MSH and a related analogue, [Nle4, D-Phe7] -alpha-MSH, were studied in a number of vertebrate species: the teleost, Lebistes reticulatus; the amphibians, Rana pipiens, R. catesbeiana, Xenopus laevis, Bufo alvarius, and B. cognatus; the lizard, Anolis carolinensis; the rattlesnake, Crotalus atrox.
(3) Two North American species of the genus Bufo (Bufo cognatus and Bufo boreas, 2n = 22) and one African species (Bufo regularis, 2n = 20) were analyzed with respect to their repetitive DNA fractions and the behaviour of their chromatin to the acid hydrolysis at different times.
(4) Autoradiographic techniques were used to measure rate of replication and length of the replication unit in cultured cells of Scaphiopus couchi, Bufo cognatus, Rana clamitans, and Triturus viridescens, having nuclear DNA amounts in the ratio 1:4:7:39 respectively.
