But, there were extremely low efficiency of integration, unstable hereditation and expression in transgenic animals by the technique.

但是，这种方法存在基因整合效率低、外源基因不能在转基因动物体内稳定遗传及表达的问题。

Transgenic organism looks like a hold of anlace,bringing great benefit to human and accusing for the security with its development.

转基因生物是把双刃剑,在给人类带利益的同时,安全性直伴随着它的发展,转基因生物的环境安全性和食品安全性。

"We are awaiting the decision from Congress and for a clearer view of the government's bill on transgenics," said Fecoagro's Pinto.

"我们正在等待国会的决定，等待政府在议案中对转基因问题作出更清晰的表态"，皮因托说。"

The results showed that the high efficiency PCR system can differentially,conveniently,effectively and coinstantaneously examine the endogenous gene Lectin and the transgenic components.

结果表明,建立的多重PCR方法能够准确的同时检测出豆粕中的内源基因和转基因成分。

It undrew the prelude of transgenic breeding that the company of Monsanto Company obtained the first transgenic tobacco plant which had resistance to tobacco virus by transgenic technique in 1986.

1986年美国孟山都公司利用转基因技术获得第株抗病毒病的转基因烟草植株，拉开转基因育种的序幕。
