Neuron Nudge 2/5
  • Identify each sequence below as belonging to DNA, RNA, or a protein.
    • TATTACGAGGCGAT
    • CCCGAAUCGAUUG
    • PTGACMFVLIDKRR
  • Which of the sequences above contains letters that are abbreviations for:
    • Amino acids?
    • Ribonucleotides?
    • Deoxyribonucleotides?
predict
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?

transcription overview
Transcription: Overview
  • Big idea: DNA  mRNA
transcription and the gene
Transcription and the Gene
  • Only one gene at a time
transcription steps
Transcription: Steps
  • Three steps
    • Initiation
    • Elongation
    • Termination
transcription steps1
Transcription: Steps
  • Initiation
    • RNA polymerase binds to promoter region and unzips DNA
transcription steps2
Transcription: Steps
  • Elongation
    • RNA polymerase reads the 3’-5’ DNA strand and creates a single-stranded mRNA in the 5’-3’ direction
transcription steps3
Transcription: Steps
  • Termination
    • RNA polymerase reaches terminator region, at which time it releases the completed mRNAand the DNA (which reforms the double helix)
