The human genome has a lot of non-coding regions, which include regulatory elements, repetitive DNA, and introns. Suppose there are two adjacent genes on a chromosome, and their positions on the chromosome are, say,
For the first gene: 11,785,723 to 11,803,245 bp.
For the second gene: 11,806,096 to 11,806,143 bp. These values include their regulatory elements, promoter and introns as well.
So what sequence is present between bases 11,803,245 and 11,806,096? Are they satellite sequences? Is this non-coding, non-regulatory region 11,803,245 to 11,806,096 bp heterochromatin?
