Unit # 8 Test will be Friday 5-13!

Translation – Step by StepTranslation – Step by Step

A ribosome attaches to the mRNA strand and tRNA molecules bring specific amino acids to the ribosome.

Translation – Step by StepTranslation – Step by Step

AUG (methionine) signals the start of protein synthesis.

Translation – Step by StepTranslation – 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

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 StepTranslation – Step by Step

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