由题干中的DNA将本题出处定位于文章末尾。第六段最后一句提到,运用DNA技术的研究证实了之前用染料的研究结果。[A]项是对文中essentially backed up the results of the earlier dye studies的同义转述,故为答案。 Barry Schwartz did not expect to feel inspired on a clothes-shopping trip. “I avoid buying...
These results indicate that the interdependent RNA replication at round 228 (Fig. 3d) can be mainly explained by the different template specificities of the three evolved replicases. The change in template specificity possibly relied on the different properties of replicases and RNAs, such as ...
DNA sequence elements involved in origin specification remain elusive. Here, we examine pluripotent, primary, differentiating, and immortalized human cells, and demonstrate that a class of origins, termed core origins, is shared by different cell types and host ~80% of all DNA replication initiation...
Genomic studies have confirmed that the cross-bred populations may have the advantage of adaptability to both climate change and diseases resistance [46, 47]. Red-Angus has been derived from the Aberdeen Angus and is becoming an increasingly popular component of the agricultural sector. This breed...
However, compatibility does not mean optimal results. Because both amplification and analysis happen in the same tube during real-time quantitative PCR, it is important to choose a qPCR tube or plate that supports both functions...
Bacterial cellschange size dramatically with change in growth rate, but the ratio between cell volume and the number of copies of the origin ofchromosome replication(oriC) is roughly constant at the time of initiation ofDNA replicationat almost all growth rates. Recent research on the inactivation...
Probability of subfamily change due to drift was computed for each subfamily drifting to each other subfamily, and a weighted average was computed for each of AluJ, AluS, and AluY, based on the expected frequency of initial subfamily membership. The results in Table 4 show that ∼7−8%...
Labeling the DNA without any prior treatment results in the fragment distribution shown here in red. An aliquot of the same sample was treated with Antarctic Phosphatase before the TdT labeling reaction, shown in blue. The size distribution of the fragments does not change, while the intensity ...
RNAi therapy has undergone two stages of development, direct injection of synthetic siRNAs and delivery with artificial vehicles or conjugated ligands; both have not solved the problem of efficient in vivo siRNA delivery. Here, we present a proof-of-prin
Current research on DNA storage usually focuses on the improvement of storage density by developing effective encoding and decoding schemes while lacking the consideration on the uncertainty in ultra-long-term data storage and retention. Consequently, th
