lation stops when the ribosome A) Runs into a repressor protein B) Becomes stuck on an operator sequence c) Reaches a stop codorn D) All of the above E) B and C 28) The numerical notation for the correct reading frame i.... A) 0 B) 1 C) -1 D) +1 E) -10 29) What is the role(s) of chaperone proteins (chaperonins)? A) They assist the ribosome in binding to the beginning of mRNA. B) They properly fold nascent proteins into their correct conformation. C) They expel proteins that misbehave. D) All of the above E) A and B 30) Which level of protein structure describes the amino acid sequence of a protein? A) Quaternary B) Primary C) Secondary D) Tertiary E) None of the above untod nr boiling at 100° C?

Explanation / Answer

27. C. When ribosome encounter a stop signal translation stops.

28. D. The numerical notation for the correct reading frame is +1.

29.B . Chaperones are responsible for the correct folding of nascent proteins.

30.B. the primary structure of proteins tells about the sequence of amino acids in protein.
