10. Question of the Day 5-9 1. Transcription makes ________ from DNA and then _________ makes proteins from _________.

11. Announcement 5-9 Unit # 8 Test will be Friday 5-13!

12. Translation – Step by Step A ribosome attaches to the mRNA strand and tRNA molecules bring specific amino acids to the ribosome.

13. Translation – Step by Step AUG (methionine) signals the start of protein synthesis.

14. Translation – Step by Step tRNA molecules continue along the mRNA strand bringing with them the corresponding amino acids. The amino acids are connected by peptide bonds

15. After the peptide bond is formed, the ribosome slides along to the next codon. The tRNA no longer carrying an amino acid is released, and a new tRNA carrying another amino acid can attach. Translation – Step by Step

16. A chain of amino acids is formed until a stop codon is reached on the mRNA strand.
