How Are Proto-Oncogenes and Tumor Suppressor Genes Different

question 198

Multiple Choice

How are proto-oncogenes and tumor suppressor genes different?

• A) Proto-oncogenes identify and correct cancer-causing mutations in DNA,and tumor suppressor genes attack irregular cell masses using the immune system.
• B) Proto-oncogenes halt cell division when DNA contains damage or errors,and tumor suppressor genes promote properly-timed cell division.
• C) Proto-oncogenes promote DNA repair when errors are detected,and tumor suppressor genes promote DNA synthesis when a sequence is error free.
• D) Proto-oncogenes cause cancer by failing to correct errors of DNA synthesis,and tumor suppressor genes cause cancer by promoting unregulated cell division.
• E) Proto-oncogenes promote cell division when a cell is ready,and tumor suppressor genes halt cell division when a DNA sequence needs correction or repair.

Definitions:

Direct Labor Cost

The total cost of employment for employees who directly contribute to the production of goods or services, including wages and benefits.

Machine-Hours

A measure of the total time that machines are operating in a manufacturing process.

Predetermined Overhead Rate

The predetermined overhead rate is calculated by dividing estimated overhead costs by an allocation base, such as direct labor hours, to allocate overhead costs to products or services.

Manufacturing Overhead

All indirect costs related to the production process, such as the costs of maintenance, supplies, and utilities, excluding direct materials and direct labor.
