Pre-ribosomes that build up in the nucleus are destroyed by the exosome, which is a multisubunit complex with exonuclease activity.
42.
A nuclease that functions by removing nucleotides from the ends of the DNA molecule is called an "'exonuclease . "'
43.
This exonuclease requires "'Mg 2 + "'in order to function and works at higher temperatures than exonuclease I.

45.
Subsequently, the chemical reaction in the exonuclease unit takes over and removes nucleotides from the exposed 3'end of the growing chain.

It has been suggested that applying a DNA exonuclease such as the Mung bean exonuclease prior to the digestion stage might eliminate such artifact.

48.
The loss of the cap results in rapid degradation of the transcript by an endogenous 5'- 3'exonuclease such as XrnI.
49.
The Chi sequence serves as a signal to the RecBCD helicase-exonuclease that triggers a major change in the activities of this enzyme.
50.
Coupling an exonuclease to the biological pore would slow the translocation of the DNA through the pore, and increase the accuracy of data acquisition.
