Given below are two statements: Statement I: A long protein chain is folded upon itself like a hollow woolen ball, giving rise to the tertiary structure. Statement II: In the secondary structure of proteins, only left-handed helices are observed. In the light of the above statements, choose the correct answer from the options given below:
Options
- ABoth Statement I and Statement II are true.
- BBoth Statement I and Statement II are false.
- CStatement I is true but Statement II is false.
- DStatement I is false but Statement II is true.
Correct answer
C. Statement I is true but Statement II is false.
Step-by-step solution
Statement I is true as the tertiary structure of a protein is formed when the long protein chain is folded upon itself like a hollow woolen ball, giving a three-dimensional view of the protein. Statement II is false because in the secondary structure of proteins, only right-handed helices are observed in nature, not left-handed helices. Therefore, Statement I is true but Statement II is false. Answer: Statement I is true but Statement II is false.
