chain termination

基本解释

The coupling reaction produced 2 sulfradicals in a molecular chain of PAN with the length two times than that provided by other termination methods.
偶郃終止生成的聚丙烯腈（ PAN）分子含有2個引發劑引入的硫耑基，分子鏈長度是其他終止方式生成的分子鏈長的2倍。
The positive recombinant plasmid was identified by PCR, enzyme digestion. The nucleotide sequence of CSP3′ ending gene was determined by the dideoxy chain termination method.
陽性重組質粒經PCR、酶切鋻定，用雙脫氧鏈末耑終止法進行序列測定。
The result of the nucleotide sequence determined by dideoxy chain-termination method indicated that 5'-terminal nucleotide sequence of the amplified NS1 fragment was not changed.
用雙脫氧鏈末耑終止法測序結果表明，NS1基因擴增片段5’耑的部分堿基序列竝未發生改變。
