what is the function of rna polymerase quiz
1. RNA polymerase unwinds the two DNA strands. 2. RNA polymerase copies the genectic instructions to form a strand of mRNA. 3. The mRNA carries the genetic instructions through the nuclear por complex into the cytoplasm to a ribosome subunit. 4. The mRNA attaches to a ribosome subunit.
RNA polymerase also recognizes signals for chain termination, which includes the release of the nascent RNA and the enzyme from the template. There are two major mechanisms for termination in E. coli.
