Answer:
The pieces can be represented by genes
Explanation:
It has been shown that the human genome contains more than 30 thousand protein‐coding genes, as well as transposable elements, repetitive and non-coding RNA sequences. These protein-coding genes are in turn composed of coding regions (exons) separated by non-coding regions (introns). The analysis of the human genome enables the scientists to identify genes associated with specific signaling network pathways and diseases.
