What is another word for noncoding DNA?
Pronunciation: [nˌɒnkˈə͡ʊdɪŋ dˌiːˌɛnˈe͡ɪ] (IPA) 
Noncoding DNA refers to DNA sequences that are not transcribed into RNA and therefore do not code for proteins. It makes up a significant portion of the human genome and its function is not fully understood. Synonyms for noncoding DNA include non-transcribed DNA, intergenic DNA, non-genic DNA, and junk DNA. Although the term "junk DNA" has fallen out of favor in recent years as research has shown that some noncoding DNA sequences may have regulatory functions, it is still commonly used. Other less common synonyms for noncoding DNA include silent DNA, non-functional DNA, and spacer DNA. Understanding the role and function of noncoding DNA remains an active area of research in genomics.
