What are the two critical steps that provide fidelity during protein synthesis? The binding of each amino acid to a specific tRNA and the complementary interaction between each mRNA codon and tRNA anticodon The specific selection and formation of specific nucleotide bonds The specific RNA capping and RNA polyadenylation The specific selection of dNTP during DNA replication and the specific binding of RNA polymerase to the promoter region of the gene The specific binding of the protein to the cis regulatory region and the specific interaction of RNA polymerase

In the activation of an amino acid for protein synthesisGroup of answer choicestwo separate enzymes are required, one to form the aminoacyl adenylate, the other to attach the amino acid to the tRNAmethionine is first formylated and then attached to a specific tRNAthe amino acid is attached to the 5 end of the tRNA through a phosphodiester bondthere is at least one specific aminoacyltRNA synthase and one specific tRNA for each amino acidAll of the above

During the process of translation:Select one:a. The incoming tRNA must first bind to the E siteb. Initiation begins with the binding of the ribosomal larger subunit to the polyA tail of the mRNAc. The peptide is passed from tRNA in the P site to the tRNA at the A sited. The mRNA is translated by one ribosome at a time

Arrange the following steps of protein synthesis in the proper order.1) DNA is transcribed to mRNA.2) tRNA pairs with mRNA.3) mRNA passes from nucleus into cytoplasm.4) Peptide bonds form.Multiple Choice4, 3, 1, 21, 2, 4, 21, 4, 3, 21, 2, 3, 41, 3, 2, 4

How is translation initiated?Group of answer choicesTwo ribosomal subunits bind to the mRNA transcript.DNA helicase binds to the origins of replication.RNA polymerase binds to the promoter sequence.Two ribosomal subunits bind to the DNA sequence.

Accuracy in the translation of mRNA into the primary structure of a polypeptide depends on:Select one alternative:amino acids being attached to tRNA molecules that contain the correct codon.the anticodon binding to the corresponding codon.small ribosomal subunits binding to specific large ribosomal subunits.ribosomes binding to specific mRNA molecules.
