GO:0000166,MF,"nucleotide binding","Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.",IEA
GO:0000287,MF,"magnesium ion binding","Interacting selectively and non-covalently with magnesium (Mg) ions.",IDA
GO:0003729,MF,"mRNA binding","Interacting selectively and non-covalently with messenger RNA (mRNA), an intermediate molecule between DNA and protein. mRNA includes UTR and coding sequences, but does not contain introns.",IBA
GO:0005634,CC,nucleus,"A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.",IEA
GO:0005737,CC,cytoplasm,"All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.",IDA
GO:0005886,CC,"plasma membrane","The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.",IEA
GO:0006402,BP,"mRNA catabolic process","The chemical reactions and pathways resulting in the breakdown of mRNA, messenger RNA, which is responsible for carrying the coded genetic 'message', transcribed from DNA, to sites of protein assembly at the ribosomes.",TAS
GO:0008152,BP,"metabolic process","The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.",TAS
