Question: Structural levels of protein structure and their descriptions

Answer: Primary- shapeless strand of amino acids; sequence. Secondary- twisted into alpha helices and pleated sheets; hydrogen bond. Tertiary- form three dimensional shape; Van der Waal interactions. Quaternary- protein subunits forming a complex structure; not all proteins have this structure.

Question: How do the nucleus and ribosomes work together to generate a protein?

Answer: In the nucleus, an mRNA copy of a gene is produced which ribosomes use as instructions to synthesize (build) a specific protein.

Question: Which event occurs during eukaryotic translation termination?

Answer: The ribosomes dissociates from the mRNA and the stop codon is recognized by a protein.

Question: Which event occurs during eukaryotic translation initiation?

Answer: The small ribosomal subunit binds with a specific tRNA to the mRNA and scans for a start codon.

Question: Which event occurs during eukaryotic translation elongation?

Answer: A tRNA binds a codon and the ribosome adds amino acids from each tRNA to the polypeptide chain.

Question: Elements of prokaryotic translation

Answer: Uncharged (unbound) tRNA, uncharged tRNA exit site, codon-anticodon pairing site (A Site), peptidyl active site, mRNA to be translated, unbound charged tRNA

Question: mRNA

Answer: A linear sequence of ribonucleotides transcribed from DNA that carries instructions for protein production.

Question: Peptide bond

Answer: A covalent bond formed when the carboxyl group of one molecule reacts with an amino group of a different molecule.

Question: Order of events that take place during translation and protein synthesis (building)

Answer:

Question: tRNA

Answer: A cloverleaf-shaped structure of ribonucleotides that contains an anticodon and is attached to an amino acid.
