RNA Polymerase
1. RNA polymerase binds to an unwound DNA and unwinds it. Creates initiation bubble. 2. RNA polymerase bonds to the promoter region of the DNA.

5. The amino acids form proteins.
SummaryFirst, the RNA polymerase binds to an unwound DNA and unwinds it.
This creates the initiation bubble. Then, the polymerase binds to the promoter region of the DNA strand. Next, the polymerase reads the DNA and creates the mRNA. The RNA hits the stop codon, and stops making the mRNA. The mRNA leaves the nucleus and enters the cytoplasm.
Then we move on to translation. First, the rRNA forms to the ribosome. Then, the mRNA binds with the rRNA and reads the first codon in the strand. The tRNA brings in the anticodon, which is the opposite, or complementary, to the mRNA strand. The amino acids attach and start to form the polypeptide chain. Finally, the ribosome hits the stop codon on the mRNA and they form the proteins needed to survive.
