DNA can determine where and when genes are expressed, but the full set of sequence determinants that control gene expression is unknown. Here, we measured the transcriptional activity of DNA sequences that represent an ~100 times larger sequence space th
SINEs (Short INterspersed Elements or Short Interspersed Nuclear Elements) are a class of dispersed and mobile DNA sequences (less than 500 basepairs (bp) in length) that are propagated through a replicative mechanism called retro- transposition, in which a RNA intermediate is reverse-transcribed ...
AsCl5在150K下的X射线衍射数据证实了在固体中存在离散的三角双锥体分子。 15.8 Oxides of nitrogen 氮的氧化物 与第IVA族元素一样,第VA族的第一个元素在形成氧化物时被分开,其中(p-p)π键合是重要的。表15.6列出了氮氧化物的一些性质,不包括NO_3,这是一种不稳定自由基物种。二氧化氮与四氧化二氮处于平衡状...
(eRNAs). Short RNAs (<500 bp) that are transcribed from enhancers, with many similarities to promoter-upstream transcripts (PROMPTs). ATAC-seq Assay for transposase-accessible chromatin; a method for identifying accessible regions of the genome, based on transposase activity. CpG islands Genomic ...
In Access Manager, the transfer service isSAMLAwareServlet. The base of the transfer service URL ishttp(s)://access-manager-host.domain:port/deploy-uri/SAMLAwareServlet. The URL is appended with the location to which the user is requesting access (?TARGET=URL-of-destination). ...
It is 1223 bp long with imperfect terminal inverted repeats of 22 bp and insertion resulted in a duplicated 8 bp target sequence in vapA. ISAS 1 expressed a 42,000 molecular weight ( M r ) protein in mini-cells. ISAS2 was 1084 bp long, expressed proteins of M r 38,000 and 39,000...
Using multi-strain whole genome microarrays, we show that there is enormous diversity of MGE carried within a MRSA CC22 SCCmecIV population, even among isolates from the same hospital and time period. MGE profiles were so variable that they could be used to track the spread of variant ...

A long-standing mystery in the field of Polycomb and Trithorax regulation is how these proteins, which are highly conserved between flies and mammals, can
