Transcription and Translation

Which of the following best shows transcription?

• DNA → RNA

• RNA → Protein

• DNA → Protein

• RNA → DNA

Which of the following best shows translation?

• DNA → RNA

• RNA → Protein

• DNA → Protein

• RNA → DNA

What is initiation?

• RNA polymerase binds to a promoter, which is a specific sequence within a gene.

• RNA polymerase moves down the strand 3’-5’, creating a 5’-3’ strand. DNA zips shut as it moves down.

• mRNA and RNA polymerase are detached from the DNA.

What is elongation?

• RNA polymerase binds to a promoter, which is a specific sequence within a gene.

• RNA polymerase moves down the strand 3’-5’, creating a 5’-3’ strand. DNA zips shut as it moves down.

• mRNA and RNA polymerase are detached from the DNA.

What is termination?

• RNA polymerase binds to a promoter, which is a specific sequence within a gene.

• RNA polymerase moves down the strand 3’-5’, creating a 5’-3’ strand. DNA zips shut as it moves down.

• mRNA and RNA polymerase are detached from the DNA.
