C.A-site of the 70 S initiation complex is ready to accept an incoming aminoacyl-tRNA.
D.IF-3 and IF-1 bind 30 S subunit.

Facility-Level Costs

These are the costs that are necessary to operate a facility, such as a manufacturing plant or a warehouse, and do not vary significantly with production volume.

Overhead Cost

Expenses related to the ongoing operational costs of running a business that are not directly tied to the production of goods or services.

Traditional Costing System

A costing methodology that allocates overhead costs to products based on a predetermined rate, often using direct labor hours or machine hours as the allocation base.

Activity-Based Costing System

A costing methodology that assigns costs to products or services based on the activities that go into producing them, providing detailed insights into the actual consumption of resources.
