| GO:0006397 | mRNA processing | biological_process | Any process involved in the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide. [GOC:mah] |
| GO:0004518 | nuclease activity | molecular_function | Catalysis of the hydrolysis of ester linkages within nucleic acids. [ISBN:0198547684] |
| GO:0090305 | nucleic acid phosphodiester bond hydrolysis | biological_process | The nucleic acid metabolic process in which the phosphodiester bonds between nucleotides are cleaved by hydrolysis. [GOC:dph, GOC:tb] |
| GO:0003676 | nucleic acid binding | molecular_function | Binding to a nucleic acid. [GOC:jl] |
| GO:0005730 | nucleolus | cellular_component | A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome. [ISBN:0198506732] |
| GO:0006388 | tRNA splicing, via endonucleolytic cleavage and ligation | biological_process | Splicing of tRNA substrates via recognition of the folded RNA structure that brings the 5' and 3' splice sites into proximity and cleavage of the RNA at both the 3' and 5' splice sites by an endonucleolytic mechanism, followed by ligation of the exons. [GOC:krc, ISBN:0879695897, PMID:9582290] |
| GO:0005654 | nucleoplasm | cellular_component | That part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653] |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
