RNAs running the show: riboswitches raise some interesting questions about genetic regulationComing from various directions, a number of research groups stumbled upon a naturally occurring mechanism for gene control that depends solely on RNA and environmental cues. ...
aAnother structure feature of eukaryotic DNA important to gene expression is methylation (see Fig.2.13 ). eukaryotic脱氧核糖核酸另一个结构特点重要对基因表达是甲基化(看见Fig.2.13)。[translate] a我们一直走到天黑 We arrive darkness continuously[translate] ...
(5) Gene expression studies commonly test for the upregulation or downregula- tion of genes between populations in similar environments (genetic differences in expression) or between environments for a given population (environmental influences on expression) (Gilad et al., 2009; Pavey et al., ...
These are very complicated questions about which I am wary of giving an ill-considered answer. Hamilton was a great proponent of the importance of sexual selection in keeping the gene-pool free of deleterious mutations (survival makes no difference if you do not reproduce) but he does not ...
Histone modifications can disrupt DNA packaging in ways that make genes either too accessible or inaccessible for gene expression, depending upon how the modification affects the folding of the chromosomal DNA.TrueFalse true Your microbiome is similar to your genome in that it is stable from birth ...
Chromatin and gene expression: constant questions, but changing answers. Cell 79:397–406 - Lewin - 1994 () Citation Context ...90a). It is not clear, however, whether these observations apply to mammalian cells. While much has been learned about chromatin structure at small scales (<100 ...
Lingering Questions about Enhancer RNA and Enhancer Transcription-Coupled Genomic Instability 来自 掌桥科研 喜欢 0 阅读量: 58 作者:G Rothschild,U Basu 摘要: eRNAs may function to regulate promoter–enhancer interactions within TADs. Enhancer regions are targets of DNA-altering events (e.g., ...
Gene expression with no selective advantage. A necessary concept but one that in practice is hard to demonstrate, not least because the strength of selective effects relevant to the evolutionary process is typically more subtle than the effects measured in the laboratory. Selective advantage may be ...
Fundamental questions about genes, inactivity, and chronic diseases How and why these interactions occur are fundamental questions in biology. Finally, a perspective to future research in physical inactivity-gene interaction ... FW Booth,SJ Lees - 《Physiological Genomics》 被引量: 561发表: 2007年 ...
