摘要

Because the origin of repeated sequences may date back to the appearance of the first genes and genomes on Earth, they must have been involved in the entire history of genome evolution. Repeated sequences are important components of the primitive genomes that would provide the basis for the origin of split genes. In this sense, introns existed in early genes, and both repeated sequences and introns have always had structural and evolutionary roles. The evolution of the composition of organic genomes may be unified in a general pattern.
