and synthesizes a complementary strand of DNA (red). B) When DNA polymerase randomly incorporates a fluorescently labeled ddNTP base, synthesis terminates. This step produces a mixture of newly ...

The labeled nucleotides were incorporated ... only very small fragments of DNA were being synthesized along the lagging strand. As the chases increased in length, giving DNA more time to replicate ...

DNA strand displacement circuits are inching closer to becoming cellular machines. Scientists are finding ways to make these programmable nanodevices stable and functional inside living cells. If ...
