What would happen if there was an error in the aminoacyl tRNA synthetase enzyme that has an anticodon of AAA but was attached to a lysine?
Can you explain why a mixture of poly A and poly U nucleotides wouldn’t incorporate leucine into a protein?

Expert Solution

If this happened, the protein coding will be wrong and the protein that is formed will be incorporating lysine instead of the phenylalanine that is normally coded by the AAA anticodon. Hence there would be a mutated protein.

The poly A and poly U nucleotides wouldnt incorporate into a protein because before this poly A tail of mRNA there is a 3'UTR that doesnt get translated and hence doesnt let the poly A of the mRNA to get translated. As for the poly U, it acts as a termination sequence for the mRNA and hence doesnt get translated.

If you have any query kindly comment before giving thumbs up. Thank you.

An aminoacyl-tRNA exhibits which one of the following characteristics? A. It is produced by a synthetase that is specific for the amino acid, but not the tRNA B. It is composed of an amino acid esterified to the 5’ end of the tRNA C. It requires GTP for its synthesis from an amino acid and a tRNA D. It contains an anticodon that is complementary to the codon for the amino acid Concerning generation of ATP from glucose during glycolysis...

The enzyme that synthesizes the neuropeptide discussed in question 1 is tyrosyl-tRNA synthetase. (PLEASE ANSWER ALL 3 PARTS!!!!!!!!) A) This enzyme requires ATP to synthesize the dipeptide, but in the ribosome peptide bond synthesis requires no ATP, why? B) You are a scientist who wants to study this enzyme-outline a set of experiments you would perform to produce recombinant protein. You must be specific in your strategy. (i.e. you can’t just say that you will purify the protein-you must indicate how)....
