Explain chromatin remodeling. What is it and what does it do to DNA? Some aspects of DNA replication are different in prokaryotes and eukaryotes; others are the same. List the similarities and differences. What are the different types of chromatin?
In which part of the gene do you expect to see a non-synonymous variation? What is genetic technology? What is acetylation and how does it cause an effect on gene expression? Define gene, trait, and chromosome. Briefly explain why you have two of every gene. ...
(b) How does the acetylation of histone proteins affect gene activity near the acetylation? DNA methylation is a mechanism used by eukaryotes to do what? What is the effect of mutations on the structure of proteins? Some transposons replicate when they move. What effect does this have on the...
“一种语言在世界上有大量增长的需求，本身就表现出这个国家、这个民族在世界的地位、它的综合国力以及它在世界上的形象，更重要的是表现各国对这个国家未来的预测。”章新胜对媒体说。北京大学教授、世界汉语教学学会会长陆俭明说，汉语在法国发展势头很快，英语、日语、西班牙语的年增长率是2％～4％，汉语则高达38％...
In this paper, the Schlick group used their mesoscale chromatin model to reveal that the 55-kb HOXC gene cluster forms a dynamic chromatin structure modulated by the cooperation of H1 concentration, nucleosome positions, and acetylation patterns. This work emphasizes the complex coordination of various...
By masking the positive charge of Lys, acetylation reduces electrostatic interactions between DNA and histone tails, thus increasing accessibility. Histone Lys ubiquitylation Covalent addition of an ubiquitin molecule to Lys residues of histones. The Polycomb repressive complex 1(PRC1) monoubiquitylates ...
