Explanation:
Proto-oncogenes are normal genes in cells that regulate cell growth and division. However, if these genes are mutated or activated, they can become oncogenes, which promote uncontrolled cell growth and division, leading to the development of cancer. Several proto-oncogenes have been identified in normal cells, and when activated, they can turn into oncogenes, potentially leading to the transformation of the cells into cancer cells.
The correct sequence of words to complete the paragraph is "proto-oncogenes, oncogenes." The other options presented include "oncogenes, proto-oncogenes," "cellular oncogenes, proto-oncogenes," and "cellular oncogenes, oncogenes," but none of these accurately reflect the relationship between proto-oncogenes and oncogenes.
In summary, proto-oncogenes are normal genes that can become oncogenes if they are mutated or activated. Several proto-oncogenes have been identified in normal cells, and when activated, they can turn into oncogenes, which can lead to the development of cancer.

Proto-oncogene is a normal gene which, when altered by mutation, becomes an oncogene that can contribute to cancer. Proto-oncogenes may have many different functions in the cell. Some proto-oncogenes provide signals that lead to cell division. Other proto-oncogenes regulate programmed cell death (apoptosis). The defective versions of proto-oncogenes, known as oncogenes, can cause a cell to divide in an unregulated manner. This growth can occur in the absence of normal growth signals such as those provided by growth factors. A key feature of oncogene activity is that a single altered copy leads to unregulated growth.
