So , we analysed its characterization . it consists of 2 . 8kb cdna with 1362bp orf and codes 454 amino acids with only a sh2 domain 8kb ，由9个外显子和8个内含子组成，编码的蛋白质有454个氨基酸，含有一个sh 。
The intron of the gene have similar characteristics with the lfy like of many plant species . the gene contain two introns and three exons 从内含子边界特征和多种植物leafy基因同源性比较，确定了该基因的内含子位置。
In addition , some experiments indicated that the introns had a major effects on transcription rather than mrna processing or stability 此外，有实验进一步表明与对rna的剪切和加工作用比较，内含子在转录调控方面作用显得更为重要。
The dna sequencing shows that thl1 gene occupies a fragment of 719 bp in gdna , which occurs in cdna with a length of only 430 bp 序列分析首次表明，克隆的thl1基因有两个内含子，大小分别为207bp和82bp ，碱基完全相同， cdna序列编码117个氨基酸。
Like eukaryotes , but unlike bacteria , they have introns in their transfer rna , but like bacteria they have polycistronic operons ( gene regulators ) 像真核生物而不像细菌，转运rna中含有内含子，还有细菌不具备的多顺反子的操纵子（基因的调控子） 。
One of them was forecasted to produce transcript factor binding site in intron 6 of silky tyrp1 . gel - shift result of this mutation proved that there is transcript factor binding site around the mutated site 经过预测，发现其中的一个snp可能使丝羽乌骨鸡的内含子6中出现了新的转录因子的结合位点。

Its at content is 51 . 61 % . the whole gene consists of five exons and four introns . the mean at values for all the exons and all the introns are 49 . 35 % and 62 . 23 % respectively 野桑蚕-淀粉酶基因全序列的at为51 . 61 ，包含5个外显子和4个内含子，外显子的at平均值为49 . 35 ，内含子的at平均值为63 . 23 。
Better yet , it only goes into a few specific places in the genome - - and these are not obviously as safe as the aav site , because they tend to be in the gaps in the middle of genes called introns 尤其可贵的是，它只进入基因组的少数特异位置?这些明显地不如aav位点那么安全，因为它们倾向于进入称为内含子的基因中间缝隙。
The results of pcr and sequencing showed that the hsp70 may contained intron ( s ) in the position of the 1 ~ 547 bp sequence of cdna , and there is no intron in the position of the 548 ~ 2090 bp sequence Pcr及测序结果分析显示hsp70cdna的1 547bp碱基所对应的基因组序列可能含有内含子， 548 2090bp碱基所对应的基因组序列不含内含子。
