Retrotransposon insertions of nonfunctional sequence occurring faster than evolution can eliminate it. 逆轉(zhuǎn)錄因子插入非功能性排序事件比進化能夠清除它要快得多。
CpG island demethylation facilitates gene transcription, resulting in oncogene activation, chromosome instability, mutation hotspot, and retrotransposon replacement. CpG島高甲基化抑制基因轉(zhuǎn)錄表達,導(dǎo)致眾多抑癌基因轉(zhuǎn)錄沉默(transcription silencing),蛋白表達缺鄭州大學(xué)2 003年碩士研究生畢業(yè)論文胃瘡中環(huán)氧合酶一2基因5’端cpG島去甲基化與蛋白表達的關(guān)系及臨床意義(中文摘要)失。
Finally, little or no thought seems to have been given to the havoc that could be wreaked upon the human genome by GM crop retrotransposon running amok within humans and farm animals. 最后,似乎很少或根本沒有人認為喜愛以轉(zhuǎn)基因作物逆轉(zhuǎn)座子橫行與人類和家畜的形式來發(fā)泄到人類基因組之上的浩劫。
Nearly 900 solo LTR of the RIRE 10 retrotransposon exist in rice genome, apart from those LTRs that flank 65 intact RIRE retrotransposons. 除了 6 5個完整的逆轉(zhuǎn)錄轉(zhuǎn)座子所具備的兩個LTR外 ,水稻基因組還含有近 90 0個RIRE10的solo LTR。
They share sequence homology and show sequence similarity 89.1% and 70.1% to the LTR of rice retrotransposon RIRE8, respectively.SLTR1 and SLTR2 are of gypsy retrotransposons of rice. 序列比較發(fā)現(xiàn),SLTR1和SLTR2存在著較高的同源性,并與水稻逆轉(zhuǎn)座子RIRE8的LTR序列高度同源,分別為89.
