The nonsense-mediated decay pathway for nuclear-transcribed mRNAs degrades mRNAs in which an amino-acid codon has changed to a nonsense codon; this prevents the translation of such mRNAs into truncated, and potentially harmful, proteins [goid 184] [pmid 10999600] [evidence NAS]; The process whereby new strands of DNA are synthesized. The template for replication can either be an existing DNA molecule or RNA [goid 6260] [pmid 16488880] [evidence IMP]; The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway [goid 6281] [pmid 16488880] [evidence IDA]; Any process involved in the conversion of one or more primary RNA transcripts into one or more mature RNA molecules [goid 6396] [pmid 8855285] [evidence TAS]; The directed movement of mRNA from the nucleus to the cytoplasm [goid 6406] [pmid 16488880] [evidence TAS]; Any process that modulates the frequency, rate or extent of translational termination [goid 6449] [pmid 9620853] [evidence IMP]; Any process that modulates the frequency, rate or extent of translational termination [goid 6449] [pmid 10999600] [evidence NAS]; The progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. Canonically, the cell cycle comprises the replication and segregation of genetic material followed by the division of the cell, but in endocycles or syncytial cells nuclear replication or nuclear division may not be followed by cell division [goid 7049] [pmid 16488880] [evidence IMP]
