histone dna gene
解釋
組蛋白脫氧核糖核酸基因-
However, it is difficult to relate the histone acetylation level with the gene expression level. we indicate, although histone acetylation acts to enhance the access of transcription - associated protein to dna, the activation of gene expression only need containing some acetylation level, but the hyperacetylation and underacetylation would effect the gene expression, so as to the abnormal development
而在克隆牛中組蛋白乙酰化水平雖然有所降低，但如果這種降低仍然為基因的表達提供了足夠的基礎，這就對基因的正常表達造不成很大影響；但如果組蛋白乙酰化水平過高或過低，可能要影響到其他因子的作用，從而影響了基因表達的調節，最終導致生物個體發育異常。 -
Arginine rich human histone h3 is a kind of basic nucleosome protein. in the medium of physiological condition, by electrostatic interaction, histone h3 which arginine impart to it a positive charge binds to dna which phosphate groups impart to it a negative charge. in this paper, in order to establish a new technology of transfection, the functional domains la and ii gene segments of pea were lined with histone h3 gene segment, then a recombinant fusion protein was constructed which serves as c arrier for transfer of dna via receptor - mediated endocytosis
本實驗在已成功獲得的pea功能區a ，功能區基因片段與人組蛋白h3基因片段的克隆菌株的基礎上，構建原核表達載體，將克隆質粒pmd - 18t - pea經nco ， mlu雙酶切，回收酶切產物；將克隆質粒pmd - 18t - h3經mlu ， xho雙酶切，回收酶切產物。
