Transcription Lesson Review

Multiple Choice

What is transcription?

• The process of replicating a DNA molecule.

• The process of making RNA using DNA as a template.

• The process of making proteins using DNA.

• The process of compliling amino acids and inserting them into DNA.

Reorder

Reorder the following steps of transcription.

• RNA polymerase binds to a strand of DNA at a promoter.

• RNA polymerase unwinds and separates the two strands of the double helix, exposing the DNA nucleotides on each strand.

• RNA polymerase adds then links complementary nucleotides

• This process continues until the RNA polymerase reaches a “stop” gene.
