interspersed repetitive elements, consisting of introns and regulatory sequences (~ 24%) , repetitive DNA (~ 59%) and non- coding DNA (~ 15%)

Why do mammalian genomes tolerate error-prone repair ? Satellite DNA in the region of centromers and telomers Coding genes separated by repetitive DNA elements (~ 1.5%) (SINE and LINE): Short and long

because > 98% of the DNA sequence is non-coding !
