Interspersed repeated DNA A)constitutes 25%-40% of most mammalian genomes. B)is located in one region of most mammalian genomes. C)is approximately 10⁵-10⁷ bp in length for each repeat. D)can be classified into gene families,such as the Alu family. E)constitutes 20%-40% of most mammalian genomes and can be classified into gene families,such as the Alu family.

Question

Quizplus · Accepted Answer

Interspersed repeated DNA constitutes a significant portion of mammalian genomes (20%-40%) and includes sequences that can be classified into gene families, such as the Alu family. These repeats are not confined to one region but are scattered throughout the genome, and their lengths vary widely, not confined to a specific range as suggested in one of the options.
