What happens when a typo slips into the genetic recipe book? This change is called a .

Scientists have discovered a way to use molecular "scissors" to edit DNA. This technology could potentially cure genetic diseases by fixing typos in the DNA code.

: Contains over 300 illustrations and "cartoon diagrams" that simplify abstract concepts.

The typo doesn't change the final protein. The cell functions normally.
