2 . sequence comparison of alpha - amylase gene of bombyx mori and bombyx mandarina the alpha - amylase gene structures of bombyx mori and bombyx mandarina are very similar , both comprised of five exons and four introns , with comparable length . the mean at contents of exons and introns are not much different 家蚕和野桑蚕-淀粉酶基因序列比较分析家蚕和野桑蚕-淀粉酶基因具有相似的基因结构,都包含5个exon和4个intron ,各内含子、外显子长度在家蚕和野桑蚕间较类似,外显子和内含子at的平均值差异不大。
Reclamation , purification and linkage of them respectively , then sequencing and analyses of according gene structure were made , results show that the complete sequence length of corresponding pcr product from brussel sprouts , kohlrabi and kale are 1665bp , 1650bp and 1650bp , containing the first two exons and introns and 22bp of the third exon 对各pcr产物分别进行回收、纯化、载体连接和序列测定及基因结构分析等,结果表明,该片段在抱子甘蓝、羽衣甘蓝和球茎甘蓝三种作物中的全长分别为1665bp 、 1650bp和1650bp ,包括相应基因的前两个外显子和内含子以及第三个外显子的22bp序列。
