(16) We suggest that receptor recognition of the HRE is analogous to that of the helix-turn-helix DNA binding motif in that the receptor binds to DNA as a dimer with the first 'zinc finger' lying in the major groove recognizing one half of the palindromic HRE, and that protein-DNA interaction is stabilized through non-specific DNA binding and dimer interactions contributed by the second 'zinc finger'.
(17) After introduction of these fusions into the chromosomal DNA of mutants affected in sacB regulation, it was possible to reveal different targets for the regulatory genes sacU, sacQ and sacS: the sacU and sacQ genes act on a region located near or just upstream from the promoter, and the sacS gene, which is involved in the induction process, acts on the palindromic structure.
(18) This regulatory sequence is about 50 base-pairs long and is centered 125 base-pairs upstream from the transcription start site in a region containing a 16 base-pair palindromic structure.
(19) These palindrome-containing vectors therefore transform such strains at a very low frequency unless a DNA fragment is cloned within the polylinker at the center of the palindrome.
(20) Gel retention assays and DNase I footprinting with the nuclear proteins of monkey cells showed that the 5'GAGGC3' pentanucleotide repeats on either side of early palindrome domain interact with monkey nuclear protein.
Sequence
Definition:
(n.) The state of being sequent; succession; order of following; arrangement.
(n.) That which follows or succeeds as an effect; sequel; consequence; result.
(n.) Simple succession, or the coming after in time, without asserting or implying causative energy; as, the reactions of chemical agents may be conceived as merely invariable sequences.
(n.) Any succession of chords (or harmonic phrase) rising or falling by the regular diatonic degrees in the same scale; a succession of similar harmonic steps.
(n.) A melodic phrase or passage successively repeated one tone higher; a rosalia.
(n.) A hymn introduced in the Mass on certain festival days, and recited or sung immediately before the gospel, and after the gradual or introit, whence the name.
(n.) Three or more cards of the same suit in immediately consecutive order of value; as, ace, king, and queen; or knave, ten, nine, and eight.
(n.) All five cards, of a hand, in consecutive order as to value, but not necessarily of the same suit; when of one suit, it is called a sequence flush.
Example Sentences:
(1) The amino acid sequence deduced from the nucleotide sequence contained both amino- and carboxyl-terminal sequences.
(2) The process of sequence rearrangement appears to be a significant part of the evolution of the genome and may have a much greater effect on the evolution of the phenotype than sequence alteration by base substitution.
