Some noncoding DNA regions, called introns, are located within protein-coding genes but are removed before a protein is made. Regulatory elements, such as enhancers, can be located in introns. Other noncoding regions are found between genes and are known as intergenic regions.Click to see full answer. Considering this, what are non coding parts of DNA?Non-coding DNA sequences are components of an organism’s DNA that do not encode protein sequences. Some non-coding DNA is transcribed into functional non-coding RNA molecules (e.g. transfer RNA, ribosomal RNA, and regulatory RNAs). what are the coding regions of DNA called? Coding DNA sequences are separated by long regions of DNA called introns that have no apparent function. Coding DNA is also known as an exon. Similarly one may ask, why do you have non coding areas of DNA? Some introns can regulate transfer RNA and ribosomal RNA activity and protein-coding gene expression. A very important non-coding sequence of DNA is called a telomere, which is a region of repetitive DNA at the end of a chromosome and protects coding DNA from being lost during cell division.What is the difference between coding and noncoding DNA?Coding DNA strand is one which codes for mRNA that will be translated later to produce protein. Non-coding strans is one which does not code for mRNA. But there is a catch. The non-coding strand is one on which the RNA is transcribed, i.e. the template strand or the strand involved in DNA:RNA hybrid.
