7. Draw a tRNA that would recognize the codon 5' A U G 3'. What is the sequence of this tRNA's anticodon? Label the ends of the tRNA (3' and 5'). Label the anticodon in your diagram, and write out the sequence of the anticodon in the context of your figure. Where is the amino acid attached? What type of bonds will form between the anticodon of the tRNA and the mRNA codon? 8. How has the mutation altered the polypeptide? Is the function of the hemoglobin molecule (which includes 2 b-globin polypeptides and 2 a-globin polypeptides) impaired? (Read your book to learn more about sickle cell disease.) 9. What is the relationship between the genotype in this case and the individual's phenotype?

Step 1
The tRNA that recognizes the codon 5' A U G would have an anticodon of 3' U A C. The 3' end of the tRNA is where the amino acid is attached. Hydrogen bonds will form between the anticodon of the tRNA and the mRNA codon. Here is a simple diagram: 5' - Amino Acid Show more…

Use the image of the tRNA shown below to answer the following questions. (a) What 2 types of bonds maintain the tRNA's shape? (1) i. ii. (b) What type of bonds form between a codon and its anticodon? (0.5) (c) Which codon would this tRNA base-pair with? Write the codon's sequence in the 5' to 3' direction. (1) [HINT: Be sure to check where the 5' and 3' ends of the tRNA are]. (d) Suppose all of the cell's copies of the tRNA shown in the figure had a "U" instead of the "G" that is labeled with a red arrow. How would this affect protein synthesis in the cell? (2.5) [Explain your reasoning and show your work for partial credit.]

3) (8 pts) Below is a diagram of two tRNAs and an mRNA in the active site of the ribosome during translation of the mRNA into protein. Three nucleotides from the sequence of each tRNA are shown for you. a. In the diagram above, label the 5' and 3' ends of each tRNA. b. In the diagram above, fill in the box attached at one end of each tRNA with the name of the amino acid that would be attached there. c. In the diagram above, fill in the boxes in the mRNA with the six nucleotides that would be present there. d. Which tRNA is about to transfer its attached amino acid over to the other tRNA and exit the active site, the tRNA on the left or the tRNA on the right?

The following diagram illustrates a step in the process of translation. Sketch the diagram and identify the following elements on it. a. $5^{\prime}$ and $3^{\prime}$ ends of the mRNA b. A, $P$, and E sites c. Start codon d. Stop codon e. Amino and carboxyl ends of the newly synthesized polypeptide chain f. Approximate location of the next peptide bond that will be formed g. Place on the ribosome where release factor 1 will bind GRAPH CANT COPY
