Scientists have discovered that DNA bases, the building blocks of DNA, can change their shape for one thousandth of a second, causing the incorporation of the wrong base pairs into the DNA double helix during DNA replication. This changes the DNA code, and such mutations are the molecular basis of evolution and genetic diseases such as cancer.
