>>10947493>RNA polymeraseDNA polymerase translates DNA to RNA via promoters / enhancers. RNA polymerase is agnostic in respect to what RNA is transcribed (turns into amino acid sequence).
For example, alien RNA inside the cell can be transcribed by RNA polymerase, this is the mechanism of action of some vaccines and gene therapy methods.
RNA polymerase is just an enzyme, like other enzymes, has an active site with high affinity for the RNA molecule which is single stranded with Uracil instead of Thymine
