hsa-mir-141_DDSD_s
The hsa-mir-141_DDSD_s (BBa_K5086107) is formed by the combination of hsa-mir-141_DDSD (BBa_K5086013), hsa-mir-141_target (BBa_K5086003) and wt (BBa_K5086017) chains. Among them, the sequence at the 5' end of hsa-mir-141_DDSD is successively complementary pair-joined to the hsa-mir-141_target and wt chains, and the sequence at its 3' end is complementary to the Universalness_h (BBa_K5086009) chain, so that hsa-mir -141_DDSD_s can bind specifically to the Universalness_h strand and thus complete the recognition of the input signal. DNA polymerase polymerizes DNA in the 5'-3' direction starting from the 3' end of the target hsa-mir-141_Rep. During DNA polymerization by Bst DNA polymerase, the wt strand is replaced and released by the newly synthesized daughter strand, which also releases a DNA single strand with the same sequence as the target At the same time, a single strand of DNA with the same sequence as the target strand (U to T) will be released, which will serve as the target for the first step of the polymerase-mediated strand displacement reaction to realize the DDSD self-enhancement process, and the wt strand will be involved in the subsequent reaction to produce a fluorescent report.
