Predict Ribosomes are the site of protein

synthesis, but they’re located outside of the nucleus. What are the pros and cons of DNA

traveling out of the nucleus to the ribosome?

What are the pros and cons of using a messenger molecule instead?

DNA vs. RNA

Transcription: Overview Big idea: DNA mRNA

Transcription and the Gene Only one gene at a time

Transcription: Steps Three steps

Initiation Elongation Termination

Transcription: Steps Initiation

RNA polymerase binds to promoter region and unzips DNA

Transcription: Steps Elongation

RNA polymerase reads the 3’-5’ DNA strand and creates a single-stranded mRNA in the 5’-3’ direction

Transcription: Steps Termination

RNA polymerase reaches terminator region, at which time it releases the completed mRNA and the DNA (which reforms the double helix)
