Answer #1

Option C. Transcribes DNA to mRNA.

RNA polymerase is an enzyme that transcribe RNA from DNA using DNA as template strand. It also transcribe the RNA from 5' to 3' direction. It is made up of many subunits. In prokaryotes there is only 1 type of RNA polymerase which transcribes mRNA , tRNA , rRNA , etc.

In eukaryotes, there are 3 main types of RNA polymerase, RNA polymerase I, II and III. RNA polynerase I transcribed rRNA, RNA pol. II transcribed mRNA, snRNA, miRNA and RNA pol. III transcribed tRNA and 5S RNA.
