Final answer:
TALEN is a DNA-cutting enzyme used in genetic engineering to edit specific regions of the DNA with precision and specificity.
Step-by-step explanation:
TALEN (transcription activator-like effector nuclease) is used in genetic engineering to edit specific regions of the DNA. It is a type of DNA-cutting enzyme that can be programmed to target and cut specific DNA sequences. By targeting and cutting the DNA at desired locations, TALENs can introduce specific changes to the genetic code, such as disabling a gene or adding new genetic material. TALENs are a powerful tool in genetic engineering because of their precision and specificity in genome editing.
