At least one nonsense suppressing tRNA is knownthat can suppress more than one type of nonsensecodon.a. What is the anticodon of such a suppressing tRNA?b. What stop codons would it suppress?c. Could this tRNA possibly also function as a missense suppressor?d. What are the amino acids most likely to be carriedby this suppressing tRNA?
Do missense mutations occur in genes encoding tRNA? Why orwhy not?
In this chapter you were introduced to nonsense suppressor mutations in tRNA genes. However, suppressormutations also occur in protein-coding genes. Using thetertiary structure of the β subunit of hemoglobin shownin Figure 9-3(c), explain in structural terms how a mutation could cause the loss of globin protein function. Nowexplain how a mutation at a second site in the same protein could suppress this mutation and lead to a normalor near-normal protein.
