One is based on the structural difference,and the other is based on the structural difference and multiple sequence alignment.

同時，本文提出了兩種RNA有害突變預測的方法国内av免费在线，一種是基于結構差異的方法；另外一種是基于結構差異與多序列序列比對的方法。

Since most of the large molecules containing phosphorus element have double bonds, it is necessary to consider the special structures of double bonds in order to deal with these large systems more accurately. So, based on density functional theory and electronegativity equalization principle, applying a general atom-bond electronegativity equalization method , using separated program, through regression and least-squares optimization , the parameters of atoms and bonds in molecules are determined . By these parameters , the charge distributions and the energy of some molecules containing phosphorus element, especial the fragment of DNA, RNA, are calculated . The results are quite good.

ARID (AT-rich interaction domain) protein is a transcription factor family in higher eukaryotes that regulates cell proliferation, development, and differentiation. Specificity of DNA binding ability in this family prefers AT-rich sequences, but some ARID family proteins are not sequence-specific DNA-binding proteins or they do not bind AT-rich sequences. We found two genes that encode ARID in Giardia lamblia genome database, garid1 and garid2. We analyzed the function of garid1 first. AU1-tagged gARID1 was found to localize to nuclei. During encystation, gARID1 mRNA level decreased emphatically, but protein level increased. We also found that gARID1 can bind AT-rich initiator of the cwp1 promoter by EMSA. Mutation analysis revealed gARID1 binding sequence was AGATC and AATAAAATA. We used ChIP to demonstrate that gARID1 can bind cwp1 gene promoter in vivo.
