Please help me with this question, i can't keep posting questions here and keep getting wrong answers!!!!!

Sapling Learning macmillan learning In E. coli, the elongation factor EF-Tu forms part of an EF-Tu-GTP-tRNA complex and increases the rate of tRNA-mRNA binding. GTP hydrolysis to GDP and Pi also enables a type of kinetic proofreading, which prevents the addition of an incorrect amino acid to the growing peptide chain. Determine which of the following statements are true. Check all the true statements. A correct match between the codon and anticodon causes a conformational change in the small ribosomal subunit and leads to GTP hydrolysis. Hydrolysis of GTP associated with EF-Tu frees the peptidyl-tRNA for peptide bond formation. A mismatch between the codon and anticodon creates a distortion in the mRNA-tRNA complex. A mismatch between the codon and anticodon does not cause conformational changes, and the Ef-Tu-GTP-aminoacyl-tRNA complex leaves the ribosome before a peptide bond can form. If the mRNA codon and tRNA anticodon match, EF-Tu-GDP leaves the ribosome. Hydrolysis of GTP associated with EF-Tu brings about a conformational change in the amino acid.

Explanation / Answer

The answers are

A mismatch between the codon and anticodon creates a distortion in the mRNA-tRNA complex.

A mismatch between the codon and anticodon does not cause conformational changes and the Ef Tu-GTP-aminoacyl tRNA complex leaves the ribosome before a peptide bond can form.
