Enhancer (genetics) A short region of DNA that can increase transcription of genes Promoter An additive that increases the activity of a catalyst. Enhancer One who enhances; one who, or that which, raises the amount, price, etc. Promoter One that promotes, especially an active supporter or ad...

Genetics and Heredity: What is the difference between poly-A or ribosomal RNA depletion library kit?RNA preparationDepending upon the need and purpose, RNA library can be prepared in many ways, for example, total RNA, targeted RNA capture, PolyA selection, riboso...
What is the effect of methylating DNA on gene expression? a. Methylation improves access of RNA polymerase enzymes to genes. b. It acts as an enhancer. c. Methylation keeps DNA tightly bound to histone proteins, making genes unavailable for transcripti Explain how DNA methylation ...
Thepromoter, a DNA sequence that liesupstreamof the RNA coding region, serves as an indicator of where and in which direction transcription should proceed. The promoter is not actually transcribed; its role is purely regulatory. While promoters vary tremendously among eukaryotes, there are some comm...
The DNA of eukaryotic genomes is wrapped in nucleosomes, which strongly distort and occlude the DNA from access to most DNA-binding proteins. An understand... E Segal,J Widom - 《Trends in Genetics》 被引量: 733发表: 2009年 Rapid periodic binding and displacement of the glucocorticoid recepto...
It is often unclear if cell types defined by different phenotypic features agree with each other nor which feature is the right one to define cell types. Furthermore, lacking a systematic approach and effort, we do not know if all the cell types in an organism have been identified and ...
Although genetics aren't the end-all, be-all when it comes to breast size, they do play some role. "Breast size is a combination of genetic and environmental factors," Dr. ... In addition, as people gain weight, their breasts also become larger." ...
What connect genetic material, DNA and RNA in genetics? What is non-genetic RNA? Into which two groups can the nitrogenous bases that form DNA and RNA be classified? What is the criterion used in that classification? What is the reproduc...
