•Structure of DNA•Structure of RNA
•I can explain how a gene codes for a protein via transcription and translation.
LEAVE THIS BLANK
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)
Transcription: Review Video #5
