• mRNA is translated at the ribosome by reading its codons (groups of three bases) • tRNA molecules carry amino acids to the ribosome, so they can be strung together in the proper sequence • the tRNA molecules have an anticodon that will pair up with the codon on the mRNA strand at the ribosome, and then drop off its amino acid. • this is how the correct amino acids are assembled in their proper order to make each protein Choose the correct sequence of tRNA bases that pair up with the bases in this mRNA strand: ACU-CCU-GAG-GAG-AAA UGA-GGA-CUU-UUU-AAA UGA-GGA-CUC-CUC-UUU TGA-GGA-CTC-CTC-TTT

A particular codon sequence of mRNA is AAA. The anticodon on the tRNA that binds to the mRNA codon is AAA. UUU. TTT. UUA. either UAA or TAA, depending on first base wobble. If AAG is the anticodon in tRNA, what is the matching codon on the mRNA? UUC. GUA. CAU. UGG. GUG. The enzyme Aminoacyl-tRNA synthetase is responsible for binding amino acids to tRNA. This requires energy from the release of two phosphates from ATP oxidizing the ATP to ADP. AFP. AMP. an enzyme. A ribosome has three tRNA binding sites, the one that releases the tRNA is Q. E. A. P. Attached ribosomes may feed their polypeptide chains (proteins) into the lumen of the endoplasmic reticulum while free ribosomes would feed theirs into the cytoplasm. There is only one initiator amino acid; it is met.
Sulav P.
Translate the mRNA and assemble the polypeptide. Assume the role of a ribosome and translate the mRNA strand from the previous question. Using the genetic code and chart below, write the sequence of amino acids encoded by the mRNA (example of how to type your answer: SER-ARG-TRP-ALA-GLY).
Adi S.
A tRNA is chemically modified so that the amino acid bound is different than the one specified by its anticodon. Which codon in the mRNA would the tRNA recognize: the one specified by its anticodon or the one that matches the modified amino acid it carries? a. The anticodon will match the codon in mRNA. b. The anticodon will match with the modified amino acid it carries. c. The anticodon will lose the specificity for the tRNA molecule. d. The enzyme amino acyl tRNA synthetase would lose control over the amino acid.
