Exonuclease — Exonucleases are enzymes (found as individual enzymes, or as parts of larger enzyme complexes) that cleave nucleotides one at a time from an end of a polynucleotide chain. These enzymes hydrolyze phosphodiester bonds from either the 3 or 5… … Wikipedia
Messenger RNA — The life cycle of an mRNA in a eukaryotic cell. RNA is transcribed in the nucleus; processed, it is transported to the cytoplasm and translated by the ribosome. At the end of its life, the mRNA is degraded. Messenger RNA (mRNA) is a molecule of… … Wikipedia
