Examples
- Scientists initially thought that junk DNA served no purpose, but recent studies have revealed that it plays a crucial role in regulating gene expression.
- The discovery of functional elements within junk DNA has led to a reevaluation of its significance in the human genome.
- Although the majority of the genome is composed of junk DNA, researchers continue to uncover new functions for these non-coding regions.
- Studies have shown that junk DNA can influence the development of certain diseases by regulating the expression of nearby genes.
- The idea that junk DNA is simply useless genetic material has been largely discredited, as evidence mounts of its importance in various biological processes.
