Explain three ways a proto-oncogene or tumor suppressor gene can lead to cancer.

Biology
1 answer:
Nimfa-mama [501]3 years ago
6 0

Proto-oncogenes signal cells to grow and differentiate. However, they can become oncogenes due to mutations which result in the uncontrollable division of the cells, i.e. cancer. One way is a point mutation in a proto-oncogene. The consequence is changed protein product. Another way is gene amplification of DNA segment containing a proto-oncogene. As the result, the encoded protein is overexpressed. The third way is translocation. As the result of translocation, proto-oncogene can be controlled by the different promoter and expressed inappropriately.

Atoms of nonmetals have a tendency to __ or__ electrons when they react.
Lera25 [3.4K]

Answer:Atoms of nonmetals have a tendency to gain or share electrons when they react.

Explanation: Non-metals are elements that gain electron to form negatively charged ions known as anions.

When non-metals react, they either gain/accept electron from a metal atom or share electron with another non-metal atom. When a non-metal accepts an electron from a metal atom, the type of bond formed is called ionic or electrovalent bond. In electrovalent bond, the metal atom transfers its valence electrons to the non-metal atom so that both attain a stable octet or duplet structure.

When a non-metal shares electron with another non-metal atom, the type of bond formed is known as covalent bond. In covalent bond, the two non-metal atoms share a pair of electron, each atom donating one electron to form a pair.

.What are the functions of the cell membrane?​
Alona [7]

Explanation:

The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out and, second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.
