Consider the following tRNAs, where the numbered forms represent the amino acids associated with them, answer briefly: PICTURE Question 1: The numbering indicates the order in which these tRNAs are recruited to the A site of the ribosome. Write the sequence of the mRNA being translated in the 5' - 3' direction Question 2: What is the amino acid sequence of the produced polypeptide? Question 3: Researchers discover that a mutation is in the anticodon of the gene encoding the proline tRNA of an individual. The anticodon sequence is normally 3' GGA 5', but in this individual the anticodon sequence is 3' GGG 5'. It appears that this individual suffers no adverse consequences. How can this be?

Give typing answer with explanation and conclusion Which of the following statements regarding the structure and function of tRNA is true? A-The codon / anticodon pairing is absolutely universal among organism. B-The charging of a tRNA does not require energy. C-There are 64 different tRNAs, one for each possible codon. D-Reading 5' to 3', the first base in the anticodon can participate in non Watson and Crick base pairing E- The 3' end of each tRNA has a unique sequence so a specific amino acid can be attached.
Refer to a genetic code table for the question. below is a portion of the template strand of a particular gene sequence. Which of the following would be the correct sequence of amino acids in the protein that this portion of the gene encodes? (Note that there are no entrance in this gene sequence, and this portion is found in the middle of the coding sequence, past the start codon, so you should transcribe and translate the entire portion of this sequence) template DNA : 3' - ACG GGT TCC TTT AAC GCG TAG -5' A) Thr-Gly-Ser-Phe-Asn-Ala B) Cys-Pro-Arg-Lys-Leu-Arg-Ile C) there is not enough information given to determine the amino acid sequence of this portion of the gene .
