The following terms, definitions and abbreviations apply to this standard. 3.1 Genetically modified feed (GMF) is a feed made from genetically modified organisms obtained through genetic recombinant technology. 3.2 Polymerase chain reaction (PCR) The template DNA is first denatured into a single strand at high temperature. Under appropriate temperature and in a buffer, two primers anneal to a complementary sequence on the two strands of the template DNA. Then, under the action of DNA synthase, four dNTFs are used as substrates to allow the annealed primers to be synthesized. After repeated cycles of denaturation, annealing and DNA synthesis, the DNA fragment located between the two primer sequences is amplified. 3.3 Qualitative detection Qualitative detection is the detection of genetically modified components in a sample to determine whether the sample is a genetically modified product. 3.4 Abbreviations 3.4. 1GMorgenetically modified organism, genetically modified organism. .3.4.2CaMy35S.35S promoter from tauliflawer ntosnn:virus 35S promoter from tauliflawer ntosnn:virus.

Qualitative detection of genetically modified feed is to use the difference between foreign genes and plant genes to design primers that can only amplify DNA fragments in foreign genes for PCR amplification. According to the experimental results, it is determined whether the feed contains foreign gene components. 5 Reagents
