Given below are two statements regarding the cellular factory responsible for synthesizing proteins: Statement I: In its inactive state, the ribosome exists as two separate subunits, a large subunit and a small subunit. Statement II: The process of translation of mRNA to protein begins when the large subunit of the ribosome encounters an mRNA. In the light of the above statements, choose the most appropriate answer f
Options
- ABoth Statement I and Statement II are correct
- BBoth Statement I and Statement II are incorrect
- CStatement I is correct but Statement II is incorrect
- DStatement I is incorrect but Statement II is correct
Correct answer
C. Statement I is correct but Statement II is incorrect
Step-by-step solution
The cellular factory responsible for synthesizing proteins is the ribosome. The ribosome consists of structural RNAs and about 80 different proteins. Statement I is correct because in its inactive state, the ribosome exists as two separate subunits: a large subunit and a small subunit. Statement II is incorrect because the process of translation of mRNA to protein begins when the small subunit (not the large subunit) of the ribosome encounters an mRNA. Therefore, Statement I is correct but Statement II is incorrect
