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.
偶合终止生成的聚丙烯腈（ PAN）分子含有2个引发剂引入的硫端基，分子链长度是其他终止方式生成的分子链长的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.
阳性重组质粒经PCR、酶切鉴定，用双脱氧链末端终止法进行序列测定。
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.
用双脱氧链末端终止法测序结果表明，NS1基因扩增片段5’端的部分碱基序列并未发生改变。
