Which of the following is the correct order of steps in translation?
1. the ribosome translocates the trna in the a site to the p site and the empty trna in the p site is moved to the e site where it is released
2. the large ribosomal subunit attaches with the initiator trna with the amino acid methionine (met) located in the p site
3. a release factor, a protein shaped like an aminoacyl trna, promotes hydrolysis and releases the polypeptide
4. a small ribosomal subunit binds to a molecule of mrna5. the anticodon of an incoming aminoacyl trna base-pairs with the complementary mrna codon in the a site

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
