I'm a tRNA that is found in the E site of a ribosome. From this, you KNOW   a. I'm participating in the formation of peptide bonds   b. I'm going to go through the P site next and lengthen the chain   c. I have no amino acid and have already passed through the A and P sites   d. I'm going to cause the ribosome to dissociate

Which of the following enzymes adds a new amino acid to the growing chain of a protein during protein synthesis?   a. aminoacyl-tRNA synthetase   b. peptidyl synthetase   c. peptidyl transferase   d. ribosomal synthetase

A single RNA molecule with many gene sequences…   a. is only found in eukaryotes   b. is not translated   c. will not have ribosome binding sites   d. is polycistronic RNA   e. is a polysome

One of the concerns with GMO is the toxicity of product by GMO when consumed by humans. Suppose that the product is to block the 16S rRNA in the proakryotic small subunit, do you think it will have a high level of toxicity? Why?   A. Yes, because the genetic code is universal.   B. No, because the genetic code is NEARLY universal.   C. No, because human ribosomes are different.
