Examplesofnucleotidenucleotide The scale bar represents the estimated number ofnucleotidesubstitutions pernucleotidesite. From theCambridge English Corpus Differences amongnucleotidesequences were due to insertions/deletions of 1- 6 nucleotides and substitution events. From theCambridge English Corpus Given the similarity of the sequences analysed, thenucleotidealignments are obvious and are not shown here. From theCambridge English Corpus Thenucleotidebinding site is located in a pocket between the two domains. From theCambridge English Corpus A protein's selectivity for a particularnucleotide, for example, is quantified in terms of its relative affinities for two different, but similar, nucleotides. From theCambridge English Corpus The nucleotides and amino acids are numbered along the upper and lower of the margins, respectively. From theCambridge English Corpus The enzyme was purified and its ability to be activated by cyclic nucleotides was examined. From theCambridge English Corpus Consistent with the observation that -butyrolactone receptors recognize the samenucleotidesequence, the residues on helix 3 are completely conserved among the receptors. From theCambridge English Corpus Thenucleotidestate of the catalytic centers together with the position of the subunit determines the conformation of the associated subunit. From theCambridge English Corpus Thenucleotidesequence of the amplicon from the water was identical to those determined from the three stool specimens for which sequencing was performed. From theCambridge English Corpus The number of heterozygousnucleotidesites maintained in a finite population due to steady flux of mutations. From theCambridge English Corpus The number of heterozygousnucleotidesites maintained in a finite population due to the steady flux of mutations. From theCambridge English Corpus Linkage disequilibrium between two segregatingnucleotidesites under steady flux of mutations in a finite population. From theCambridge English Corpus Branch lengths are proportional to the estimated number ofnucleotidechanges. From theCambridge English Corpus Genetic mapping will be further simplified by the generation of additional microsatellite markers and the development of markers based on singlenucleotidepolymorphisms.
