Final Answer:
Ribosomes consist of two separate subunits that come together as part of the initiation process and dissociate immediately after termination.
The correct option is a) two, as ribosomes indeed consist of two separate subunits that undergo assembly during initiation and dissociation after termination.
Step-by-step explanation:
Ribosomes, essential cellular structures for protein synthesis, are composed of two separate subunits. This configuration allows for a dynamic assembly and disassembly process during translation.
Ribosomes Composition: The statement correctly identifies that ribosomes consist of "two separate subunits." This aligns with the fundamental structure of ribosomes, where a large and a small subunit combine during the initiation phase of protein synthesis.
Initiation and Dissociation: The statement mentions that the subunits come together "as part of the initiation process" and "dissociate immediately after termination."
In summary, the correct option is a) two, as ribosomes indeed consist of two separate subunits that undergo assembly during initiation and dissociation after termination.
