SUMMARY
The term "gene" encompasses more than just protein-coding sequences; it includes non-coding regions that play crucial roles in gene regulation. Non-coding sequences can act as control elements, influencing the expression of nearby coding genes. Current estimates suggest there are approximately 20,000 protein-coding genes in the human genome, but the total number of genes, including non-coding ones, is significantly higher. This broader definition reflects the historical evolution of the term "gene" beyond its initial understanding.
