链条驱动机构包括一条双排辊链，通过它来驱动进气和排气凸轮轴。
The chain drive consists of a duplex roller chain which drives both intake and exhaust camshafts.
对于双链DNA分子中的一条，出现了一个问题，那就是此链的末端无法被复制。
For one of the two DNA strands, a problem exists in that the very end of the strand cannot be copied.
这种三螺旋体的稳定性极高，以至于在同型嘧啶PNA靶向双链DNA嘌呤道时，能取代其中一条DNA链侵入双螺旋。
The stability of these triple helixes is so high that homopyrimidine PNA targeted to purine tracts of dsDNA invades the duplex by displacing one of the DNA strands.
基线可作为一条单链系或双链系。
