aWhen RNA is used as template, by initially adding the reverse transcriptase, one-step process f'rom cDNA generation to DNA amplification can be achieved. 当RNA使用作为模板时,通过最初增加反向transcriptase,一步处理f'rom cDNA世代到脱氧核糖核酸放大作用可以达到。[translate]...
aWhen it cannot, then simply cloning the gene into a plasmid, which is subsequently grown in a non-modifying host and re-sequenced, can provide the match [9].Moreover, SMRT sequencing has also been able to identify RNA base modifications through the same approach as DNA base modifi...
What ingredient, when added, would lead to creating RNA/DNA in the Miller Urey experiment?Miller Urey experimentMiller and Urey conducted experiments to find out the molecular origins of life. They simulated the conditions on earth at the time of origin of life to show tha...
Finally, it has been associated with the inhibition of cellular regeneration, DNA & RNA synthesis, oxygenation of the tissues, and alteration of electrolyte activity. It has been linked directly to cardiovascular disease, arteriosclerosis, heart attacks, stroke, high cholesterol and high blood pressure...
LYCO表达卵泡细胞的标记基因Foxl 2,而LYCT表达睾丸支持细胞的标记基因Dmrt 1,且LYCO和LYCT不表达生殖细胞标志基因Vasa。表明LYCO和LYCT分别由卵泡细胞和睾丸支持细胞组成。在LYCO和LYCT中分别敲低Dmrt 1和Foxl 2后,获得的细胞系可有效用于RNA介导的干扰(RNAi)实验和基因间相互作用的研究。
However, at the individual gene level, 46 of the 219 genes did not correlate across the 51 matched FFPE and RNAlater samples. Comparing gene expression results using NanoString and qRT-PCR for 18 genes in the same pool of RNA (RNAlater), we found a significant correlation in 17/18 genes...
aSo far, the nucleic acids being separated by electrophoresis that have been discussed are in their native state. The electrophoresis condition in such a case is called non-denaturing. Denaturing conditions are used when DNA sequences are to be determined, or when the size of RNA is to be de...
