1. Daily Warm-Up Dec. 12th Transcribe this DNA segment
3’- ATCATTAAACGC – 5’
What enzyme does the transcribing? Which direction must the enzyme read the strand
Homework:
-Read 13.2
Turn in:
-12.3 questions if haven’t already

2. Translation Where did transcription occur?
Where does translation occur?
Ribosome (cytoplasm)
Made up of ribosomal RNA (rRNA)
Creation of a polypeptide
from mRNA

3. Polypeptides Composed of amino acids Codons= set of 3 nucleotides 20
Why this number?
Start codon= AUG
Stop codons= UAA, UAG, UGA

4. Translation
Ribosome takes in the mRNA and translates it from 5’ to 3’.
Transfer RNA (tRNA) brings amino acids from the cytoplasm to the ribosome.

5. tRNA and Anticodons tRNA matches up with mRNA.
Anticodons on tRNA match up with the codons on mRNA

7. Translation Steps Initiation- need start codon
Elongation- creation of polypeptide chain
Termination- stop codon

9. Translate this sequence TATAAAATCCGCAAC
