Introns are not the exception in human genes; they are the…
““Introns are not the exception in human genes; they are the rule. Human introns are often enormous-spanning several hundreds of thousands of bases of DNA. And genes themselves are separated from each other by long stretches of intervening DNA, called intergenic DNA. Intergenic DNA and introns-spaces between genes and stuffers within genes-are though to have sequences that allow genes to be regulated in context. To return to our analogy; these regions might be described as long ellipses scattered with occasional punctuation marks. The human genome can thus be visualized as: This…is……the…(...)...s...truc...ture…of…your…gen...om...e; The words represent genes. The long ellipses between the words represent the stretches of intergenic DNA. The shorter ellipses within the words (gen...ome...e) are introns. The parentheses and semicolons-punctuation marks-are regions of DNA that regulate genes.””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Most DNA between genes consists of introns and intergenic regions, which act as regulatory “ellipses” shaping gene expression.
In simple terms: DNA has large non‑coding stretches that regulate genes.
