RNA polymerase I activity

id: GO:0001054
name: RNA polymerase I activity
namespace: molecular_function
type: go
obsolete: False

Description: Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). Utilizes a DNA template that contains an RNA polymerase I specific promoter to direct initiation and catalyzes DNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. Can initiate a chain 'de novo'.
