The melting of the coding and non-coding classes of natural DNA sequences was investigated using a program, MELTSIM, which simulates DNA melting based upon an empirically parameterized nearest neighbor thermody

Over the years it has become more and more evident that our genomic DNA is pervasively transcribed. The portion transcribed into mRNAs, 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 transcr...
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...
It has been observed that non-coding DNA is mainly repetitive DNA with the same bases repeated across the genome. The geneticistLinda Partridgediscusses the concept of non-coding DNA. Table: amount of DNA and percentage copy DNA (sc DNA) in various animal species. Amount of DNA is expressed...

In subject area: Biochemistry, Genetics and Molecular Biology A cis-regulatory palindrome is a noncoding DNA sequence that is bound by sequence-specific transcription factors that control where, when, and the levels at which a gene is expressed. ...
Noncoding DNA comprises a substantial fraction of the genomes of higher eukaryotes. It consists largely of introns, simple repetitive DNA sequences, and sequences derived from mobile genetic elements (i.e. transposable elements).doi:10.1038/npg.els.0003823...
