2b. Now write the complimentary mRNA strand for the original typed strand in 2a.
2c. Write the complimentary tRNA strand for the strand you wrote in 2b.

- The figure below shows a ribosome in the process of translating an mRNA with a sequence: 5'...AUGCCGUAUGCUCUUUAA..3' a) The right side shows the ribosome with an empty A site aligned with the codon 5'UAU3'. The next tRNA to occupy the A site on the ribosome will have what anti-codon sequence (label 5' and 3')? Keep in mind the wobble pairing rules and make sure your answer is consistent with the genetic code. Explain your answer. b) Suppose, just as the ribosome started translating the mRNA, the cell suddenly lost all of its alanine tRNAs. Using the figure as a guide, draw and label the state the ribosome would arrest in.arrow_forwardChoose any pentapeptide composed of five different amino acids. List the amino acids.

- A protein had the amino acids leu-gly at codons 10 and 11. A deletion of the 5’ base of the leu codon (i.e. the first base) changed the protein so that it now reads ser-ala at codons 10 and 11.

This base pair allows a single tRNA molecule to recognize more than one codon using its one anticodon sequence. It requires a shift in position of the two nucleotides. Guanine and uracil come together in this unusual pair via 2 hydrogen bonds. Based on what you know about hydrogen bond formation and base pairing, draw a guanine nucleotide and a uracil nucleotide hydrogen bound to one another.arrow_forward
