involve interactions with other chemical and biological molecules, they allow the generation of ‘smart’ nanoscale architectures; the assembly and function of these architectures are responsive to chemical or biological stimuli, in much the same way that biomaterials are made and function in cells.

摘要: An isolated DNA with a nucleotide sequence encoding a ripening form of a xylanase fungal origin having bread improving activity. Cells are transformed with this DNA and used to produce the ripening form of xylanase which itself is suitable for use in flour and dough.收藏...

精子活力下降、精神压力、工作环境、饮食作息习惯、氧化应激、高龄、细菌感染和暴露于环境化学物质等许多因素都与精子DNA片段化有关,而DFI的升高可降低宫腔内人工授精妊娠率及体外受精(in vitro fertilization,IVF)和卵胞质内单精子注射技术...
DNA- and RNA-binding proteins (DRBPs) constitute a significant fraction of cellular proteins and have important roles in cells. Their functions include control of transcription and translation, DNA repair, splicing, apoptosis and mediating stress responses. ...
Although the "knot DNA" has previously been seen before outside of living cells under artificial conditions in a laboratory, many scientists debated whether the i-motif could exist inside living things. But by using a fragment of an antibody molecule that could specifically recognise and attach to...

in normal and diseased cells, and it can potentially function as a biomarker. Although these findings challenge the view that methylation is generally instructive for gene silencing, several open questions remain, including how methylation is targeted and recognized and in what context it affects ...
