Wild-type strains of E. coli have a tRNA with a 5′-GUA-3′ anticodon that recognizes the UAC codon for tyrosine. We can represent
this tRNA as GUA-tRNATyr. Suppose you isolated a strain of E. coli in which a mutation changed the anticodon in this tRNA to 5′-CUA-3′ (creating CUA-tRNATyr). Answer the following questions about translation elongation in each strain. For each answer, type in "yes" or "no". A. Will the wildtype tRNA recognize a normal UAC codon in the A site?
B. Will the mutant tRNA recognize a normal UAC codon in the A site?
C. Will the wildtype tRNA recognize a stop codon in the A site?
D. Will the mutant tRNA recognize a stop codon in the A site?
E. Will peptide bond formation occur with the wildtype tRNA bound in the A site?
F. Will peptide bond formation occur with the mutant tRNA bound in the A site?
G. Will the normal, wildtype protein be produced in the wildtype strain?
H. Will the normal, wildtype protein be produced in the mutant strain?
Like all organisms, humans compete with other species for basic needs in an ecosystem. Humans usually succeed because they have developed technology to help them. ... Humans have also introduced new elements to ecosystems, such as pollution. Pollution can affect all of the organisms in an ecosystem.
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
I think the correct answer from the choices listed above is option A. It is in the liver that ammonia is <span>converted to the less toxic compound urea. Most of the wastes products from the processes in our body goes to the liver. It serves as a filter in our body. Hope this answers the question.</span>
