A covalent bond in which the electrons are shared unequally is called a(n) polar covalent bond. The atoms of the bond have partial negative and positive poles due to unequal electron distribution.
An electron exchange that results in the formation of electron pairs between atoms is known as a covalent bond. When atoms share electrons, a stable equilibrium of the attractive and repulsive forces between them is known as covalent bonding. These electron pairs are also known as shared pairs or bonding pairs. Since most interactions between carbon molecules include covalent bonds, covalent bonds are particularly significant. By sharing electrons with other molecules through covalent bonds, molecules can form extensive chains of compounds.
When atoms are distributed unevenly in a covalent connection, a polar covalent bond develops. Specifically, when the two atoms in the bond have electronegativities that range between 0.4 and 1.7. Polar covalent bonds and polar bonds are frequently used interchangeably.

Answer:
D. Binding of p53 to Mdm2
It has nothing to do with Xray irradiation.
Explanation:
Mdm2 is a protein regarded as the main regulator of tumor suppressor protein P53. P53 Inactivation by mutation is seen as one of the most frequent alterations in tumors that affects humans.
The central binding p53 site of Mdm2 encloses amino acid. The binding of p53 to the central Domain is strengthened after the process of phosphorylation of the central Mdm2 domains.
Answer:
D: They have restricted cell division.
Explanation:
Pre cancerous cells often act like cancer cells and will grow at abnormal rates but unlike cancer cells they are unable to invade other organs
