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 of DNA which do not code for proteins. Some of the noncoding DNA transcribe into functional...

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...
The similarity in the distributions of such runs in the coding and noncoding regions may be due to some structural features of the DNA molecule as a whole. Runs of guanine (or cytosine) of three to six nucleotides occur predominantly in noncoding DNA regions in eucaryotes, especially in ...
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 ...

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 ...
it used to be considered "junk." Today, though this noncoding DNA is still regarded as biological dark matter, it's already known to serve as a crucial instruction manual. Among other things, it determines whengeneswithin the coding DNA—the ones that do encode proteins—are turned on and...
The years following publication of the draft human genome sequence brought about a dramatic change in our understanding of the organization and expression of genetic information. Discoveries of new classes of RNA without protein coding potential and larg
