Different types of noncoding DNA can be identified in the organisms’ genome. They are introns,repetitive DNA, regulatory DNA, etc. Repetitive DNA is different types such as telomeres, tandem repeats, and interspersed repeats. Introns are noncoding DNA found within the genes. They are segments o...
which in turn are translated into∼20,000 proteins, is minimal (2%–5%). Far from being “junk DNA”, most of the rest (75%–90%) is rather transcribed into hundreds of thousands of non-coding RNAs (ncRNAs)3that are emerging as sophisticated...
染色体的一些结构元件也是非编码 DNA 的一部分。例如,染色体末端的重复非编码 DNA 序列形成 端粒。端粒保护染色体的末端在遗传物质的复制过程中不被降解。重复的非编码 DNA 序列也形成卫星 DNA,它是其他结构元件的一部分。卫星 DNA 是着丝粒的基础,它是 X 形染色体对的收缩点。卫星 DNA 还形成异染色质,这是一种...
Noncoding DNA refers to the portion of DNA that does not encode proteins. It was previously thought to have no function, but recent research has revealed its involvement in various cellular processes such as DNA cutting and splicing, transposon reassembly, genome rearrangements, and the production ...
Noncoding DNAdoi:10.1007/978-1-4020-6754-9_11486Noncoding DNA is not translated into protein, e.g., some of the sequences of introns and intergenic regions. These sequences were considered of no or minimal evolutionary significance. Some of these sSpringer Netherlands...
The noncoding RNA LINP1 acts as a scaffold that links Ku and DNA-PKcs and enables efficient DNA double-strand-break repair through nonhomologous end joining (NHEJ), thereby enhancing the resistance of triple-negative breast cancer cells to radiation and chemotherapies. This is a preview of ...
2018,Cancer and Noncoding RNAs Journal 2015,Brain Research Introduction Non-coding RNAs, RNA-seq Technologies, and Computational Tools In recent years, with the development ofhigh throughput sequencingtechnologies, more and more non-codingRNAs(ncRNAs) have been identified.

It is evident that the size of transcribed noncoding segments of the mammalian genomes significantly exceeds the open reading frames translated into proteins. There is a growing number of genes which yield noncoding RNAs (ncRNA) playing multiple functions in regulation of gene expression. Many of ...
