Transcript
Video Use the video to fill in your table. Transcription (Notes) Transcription occurs in the nucleus Step 1: The section of DNA that has the code for the protein that is needed is unwound Step 2: RNA polymerase (enzyme) uses the DNA to make a complementary strand of mRNA Translation Step 1: mRNA carries the code from the DNA out of the nucleus to a ribosome in the cytoplasm The code is read 3 letters at a time The 3-letter groups are called codons Translation The ribosome reads each codon A tRNA with a complementary anticodon is attached Each tRNA molecule with a specific anticodon carries a specific amino acid Translation tRNA anticodon The ribosome reads each codon A tRNA with a complementary anticodon is attached Translation Each tRNA molecule with a specific anticodon carries a specific amino acid Translation The amino acids that are dropped off by all of the tRNA molecules are joined together The string of amino acids forms a polypeptide (another word for a protein)
