Susan Allender-Hagedorn and Charles Hagedorn — An Agricultural and Environmental Biotechnology Annotated Dictionary

An enzyme that digests DNA or RNA, beginning at the end of a strand. It therefore requires a free end in order to begin the degradation. 5'-exonucleases require a free 5' end and degrade the molecule in the 5'?3' direction. 3'-exonucleases require a free 3' end and degrade in the opposite direction.
