The amino acid sequence of a protein determines its structure.Which of the following statements is true?
A) Two proteins with similar amino acid sequence should have similar structures.
B) Two proteins with different amino acid sequences will have identical structures.
C) Two proteins with similar amino acid sequences will always have the same function in a cell.
D) It is impossible to determine how proteins will fold based on the amino acid sequence alone.

Quizplus · Accepted Answer

The amino acid sequence of a protein determines its structure, suggesting that proteins with similar amino acid sequences are likely to have similar structures. However, this does not necessarily mean that the proteins will have the same function in a cell. It is also possible to predict how proteins will fold based on their amino acid sequence, although this is still an area of active research. Therefore, statement A is the best choice as it accurately describes the relationship between amino acid sequence and protein structure.
