tRNA has the following sequence in its anticodon: 5'-GCT-3'
tRNA has the following sequence in its anticodon: 5'-GCT-3'. Which amino acid should be attached to this tRNA? ATG
Homework Answers
As the sequence is read from 3'-5' but here the sequence is given fro 5'-3' which is in an opposite manner so first write it as 3'-TCG-' then amino acid which attached with the code is AGC which code for serine amino acid. Hence the answer is Serine

Suppose it was possible to change the anticodon on a tRNA from 3-CCG-5'to 3-UGG- 5' after the amino acid was already loaded. Predict the result in a translated polypeptide. What if you changed the sequence prior to the amino acid being loaded onto the tRNA? O In the first case glycine would be found in the polypeptide where threonine was supposed to be. In the second case the changed tRNA would behave like a tRNA for threonine. O In the...

During elongation of proteins during protein synthesis tRNA with the amino acid that matches its anticodon binds to the codon on the mRNA. each new amino acid is first transferred to the anticodon of the tRNA. anticodons on the ribosomes recognize the codons on the mRNA and attach the correct amino acids. ribosomes move along the DNA. RNA polymerase II uses the codons on the mRNA to polymerize the protein.

A mutant yeast strain is found with a mutation affecting some of its tRNA Tyr. The wild type normally produces a tRNA that recognizes the codon 5’ UAC 3’, and is charged with the amino acid Tyrosine (Tyr) (its notation is tRNATyr). The mutant tRNA is still charged with Tyr, but the anticodon is mutated and now has the sequence 5’- UUA3’. How will some of the proteins produced in these yeast cells be different from the wild type proteins?
