What is the role of codons UAA, UGA, and UAG in translation? What events occur when one of these codons appears at the A site of the ribosome?

If a man and a woman are each heterozygous carriers of a mutation causing a disease on the RUSP list, what do you think are the three or four most important factors they should consider in their decision making about having children?

Identify the amino acid carried by tRNAs with the following anticodon sequences.

5′-GAU-3′

For each of the anticodon sequences given in the previous problem, identify the other codon sequence to which it could potentially pair using third base wobble.

Suppose a man and a woman are each heterozygous carriers of a mutation causing a fatal hereditary disease not on the RUSP list. Prenatal genetic testing can identify the genotype of a fetus with regard to this disease and can identify fetuses with the disease. What do you think are the three or four most important factors this couple should consider in their decision making about having children?

Compare and contrast the composition and structure of bacterial and eukaryotic ribosomes, identifying at least three features that are the same and three features that are unique to each type of ribosome.

Identify the amino acid carried by tRNAs with the following anticodon sequences.

5′-AUG-3′
