|
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. |
GO:0008168
|
methyltransferase activity
|
Catalysis of the transfer of a methyl group to an acceptor molecule. |
GO:0006364
|
rRNA processing
|
Any process involved in the conversion of a primary ribosomal RNA (rRNA) transcript into one or more mature rRNA molecules. |
GO:0001510
|
RNA methylation
|
Posttranscriptional addition of a methyl group to either a nucleotide or 2'-O ribose in a polyribonucleotide. Usually uses S-adenosylmethionine as a cofactor. |
GO:0008649
|
rRNA methyltransferase activity
|
Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to a nucleoside residue in an rRNA molecule. |
GO:0031167
|
rRNA methylation
|
The posttranscriptional addition of methyl groups to specific residues in an rRNA molecule. |
