Here, we developed PCR-based DNA markers derived from the LTR-retrotransposon sequence and used these markers to screen worldwide accessions of rice germplasm.

我们利用LTR反转座子序列开发出基于PCR的DNA分子标记并用来筛选世界范围内的水稻种质。

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，似乎很少或根本没有人认为喜爱以转基因作物逆转座子横行与人类和家畜的形式来发泄到人类基因组之上的浩劫。

They have been studying a retrotransposon that lost its independence to an early mammal some 70m years ago.

ECONOMIST: Some ��junk�� DNA may have a function

The result of all this genetic engineering was a system that produces light in cells in which a retrotransposon has jumped.

ECONOMIST: Brain development may be influenced by genetic parasites

Sometimes, however, a retrotransposon forgets how to have a life of its own, and is just passed down the generations along with the host's genes.
