Abstract:

All the somatic cells in an organism share the same genetic information, but have different RNA expression subsets. Only part of genes are expressed and perform their functions at a specific time. In recent years, breakthroughs in epigenetic research have helped people understand the regulation of gene expression to a certain extent. Three types of biological macromolecules: DNA, RNA, and protein, are chemically modified after synthesis. These modifications involve the regulation of almost all biological processes. So far, researchers have identified more than 17 and 160 chemical modifications in DNA and RNA, respectively. The interest in various biological functions of DNA and RNA modifications has promoted the development of the frontier fields of epigenomics and epigenomics. Developing chemical and biological tools to detect specific modifications in the genome or transcriptome is an issue of great concern to us, and it is also a key to the research of epigenomics and epitranscriptomics. Herein, we summarize the detection methods of nucleic acid modifications, and put forward some bottlenecks in the existing technologies and possible innovative methods.

Key words: Epigenetic, Nucleic acid modification, Detection technology, Sequencing
