<span>I think you meant chromosome aberration. In that case, it is when a chromosome is “abnormal,” such as having a “wrong” structure or missing a chromosome. There are four types of mutations: deletion, duplication, inversion, and translocation. The fifth is deficiency, when a chromosome is lost during the development stage of a fetus.

Cells use the proteins called receptors which can bind the signaling molecules and initiate a physiological response with the other cells.
<u>Explanation:</u>
- The cell to cell interaction is also known as Cellular interaction. The cells that can communicate with each other in three ways Gap junctions, Tight Junctions, desmosomes.
- The signaling of cells allows communicating with adjacent cells and distant cells.
- Ligand binding to the receptor allows for signal transduction in the cell. To terminate the ligand will be removed from the access with the receptor.
