AMNH Genetic and Genomic in Nursing Practice Exam

Oncogenes are crucial components in the regulation of cellular functions, particularly relating to cell growth and division. The hallmark function of an oncogene is to promote the process of cell division, which, when dysregulated, can lead to uncontrolled cell proliferation and tumor formation. These genes are typically mutated or overexpressed forms of normal genes called proto-oncogenes, which are involved in normal cellular functions that promote growth and division.

In the context of cancer, when an oncogene is activated, it can drive the transformation of a healthy cell into a cancerous one, perpetuating rapid and uncontrolled growth. This process is significant because it reflects the mechanisms through which cancer can develop and progress, leading to tumorigenesis.

Understanding the role of oncogenes is essential in nursing and healthcare because interventions targeting these genes may be developed for cancer therapies, illustrating the importance of genetic and genomic knowledge in nursing practice.
