The cyanophage contained a double - stranded dna genome at ca . 36 . 6kb
The genetic material of the new virus is arranged in a similar fashion , encoded in circular , double - stranded dna , and the virus ' s five proteins have similarities to the proteins of other polyoma viruses
To investigate the silence effect of hela cells " telomerase gene expression after shrna based on human telomerase htert transfected into cells . methods : we constructed a partial double - strand dna with t7 promoter as dna template and synthesized small hairpinrna in - vitro using t7 rna polymerase
Conclusions : the in - vitro method that partial double - strand dna with t7 wi l . - toi promoter sequence as template and synthesizing by t7 rna polymerase can product high yield , excellent purity shrna . lt is a convenient - , effective ^ low - cost method and fit for small rna synthesis and rna interference researches in ordinary laboratory
The mechanism is that the introduced complementary oligonucleotides can bind to the corresponding mrna or double - stranded dna in genome and form partial double - stranded molecules or triple - stranded nucleic acid molecules by sequence - specific and nonsequence - specific antisense action , thus the target gene will be orientationally blocked and expression of the target inhibited so that therapeutic effect could be attained . in this study , we designed a fragment of human c ii ta cdna in antisense orientation using mrna of c ii ta as template . the primers were designed based on 94 - 500 nucleotides segment in 5 " end of ciita gene so that the interested gene contained 407 base pairs which included two aug codons in 1 16 and 188 nucleotides as well as the splicing site between the first and the second exons
