During protein synthesis, two subunits of ribosomes associate. Mg2+ is essential for it. Soon after the completion of protein synthesis, the subunits separate. The phenomenon is called dissociation.

Assertion: The subunits of ribosomes come together only at the time of protein formation.
Reason: Mg2+ causes their association or dissociation.
Explanation:
Ribosomes are complex molecular machines composed of small and large subunits. These subunits come together during protein synthesis and dissociate after the process is complete.
Role of Mg2+:
Magnesium ions (Mg2+) play a crucial role in ribosome function. They are required for the association and dissociation of ribosomal subunits.
Mg2+ and Ribosome Association:
During the initiation of protein synthesis, the small and large ribosomal subunits come together to form a functional ribosome. This process is mediated by Mg2+ ions. Mg2+ ions help stabilize the interaction between the ribosomal subunits, allowing them to associate and form a complete ribosome.
Mg2+ and Ribosome Dissociation:
After protein synthesis is complete, the ribosomal subunits dissociate from each other. Mg2+ ions also play a role in this process. They help destabilize the interaction between the subunits, allowing them to separate and return to their individual forms.
Explanation of Assertion:
The assertion that the subunits of ribosomes come together only at the time of protein formation is true. Ribosomal subunits exist separately in the cell until protein synthesis is initiated. At that point, they associate with the help of Mg2+ ions to form a functional ribosome.
Explanation of Reason:
The reason given for the assertion is also true. Mg2+ ions cause the association or dissociation of ribosomal subunits. They help stabilize the interaction between the subunits during association and destabilize it during dissociation.
Correct Answer:
Both the assertion and the reason are true, but the reason is not the correct explanation of the assertion. While the reason provides additional information about the role of Mg2+ ions in ribosome association and dissociation, it does not directly explain why the subunits come together only during protein formation. The association and dissociation of ribosomal subunits also involve other factors and processes.
