What is the difference between coding and non coding regions of DNA?
Thereof, what are coding and non coding region of DNA?
Non-coding DNA sequences are components of an organism's DNA that do not encode protein sequences. Other functions of non-coding DNA include the transcriptional and translational regulation of protein-coding sequences, scaffold attachment regions, origins of DNA replication, centromeres and telomeres.
Similarly, what are non coding regions of a gene called? 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.
Hereof, what is coding strand of DNA?
When referring to DNA transcription, the coding strand is the DNA strand whose base sequence corresponds to the base sequence of the RNA transcript produced (although with thymine replaced by uracil). By convention, the coding strand is the strand used when displaying a DNA sequence.
What is non coding DNA used for?
In genetics, the term junk DNA refers to regions of DNA that are non-coding. Some of this noncoding DNA is used to produce noncoding RNA components such as transfer RNA, regulatory RNA and ribosomal RNA.
