What is the role of tRNA in protein synthesis?

Protein synthesis Someone help me!!!! Exams soon?

  • I wanted to ask about tRNA and it's role in protein synthesis here's what I think: after the mRNA leaves the nucleus it goes to the ribosome(site of protein synthesis) 3 bases on a mRNA are the codon which code for 1 amino acid, the tRNA has 3 bases? ie AUG and takes it to the ribosome to the mRNA strand for complementary base pairing so this particular tRNA will go to the part of the mRNA that has UAC these proteins form covalent bonds (peptide bonds) and the process continues, I can't imagine this because my book says the tRNA carries amino acids to the ribosomes and then another book says about how the tRNA carries 3 bases (anticodons)?? I don't understand is the tRNA a large molecule that carries these bases and in these bases there amino acids?? I don't get it someone explain it to me simply please I have exams please thank you!!

  • Answer:

    The tRNA carries the protein into the ribosome. Each tRNA has 3 bases, called anticodons. A codon codes for one amino acid. A tRNA has only one anticodon, so therefore can only carry one amino acid. I'm not sure if this fully answered your question, but I did find a video that might help you too. http://www.youtube.com/watch?v=Ikq9AcBcohA
