Translate the following passage into Chinese. Par.3 It is put forward in the risk assessment documents that the GM components of transformed plants are completely destroyed in the digestive tract of humans and animals, together with the other genetic material found in them. However, foreign DNA plasmids5 are steadier against the digestion than it was originally believed. Plasmid DNA and GM DNA were found in microorganisms of the intestine and in saliva (Mercer et al. 1998; Coghlan 2002). Experimental researches in mice showed that ingested foreign DNA can persist in fragmented form in the gastrointestinal tract, penetrate the intestinal wall, and reach the nuclei of leukocytes白细胞, spleen脾细胞and liver cells (Schubbert et al. 1994) Par.3 ... In another research of Schubbert et al. (1998) Foreign DNA, orally ingested by pregnant mice, was discovered in blood (leukocytes), spleen, liver, heart, brain, testes and other organs of foetuses and newborn animals. They considered that maternally ingested foreign DNA could be potential mutagens for the developing fetus. However,Brake and Evenson (2004) yzing the testis in mice as a sensitive biomonitor of potential toxic, didn’t find negative effects of transgenic soybean diet on fetal, postnatal, puber talor testicular development.
