DICENTRIC Meaning and
Definition
-
Dicentric is an adjective commonly used in the field of genetics and cell biology to describe a specific chromosomal abnormality. In simple terms, it refers to a chromosome that has two centromeres instead of the typical single centromere. The centromere is an essential part of the chromosome that plays a role in chromosome segregation during cell division.
The occurrence of a dicentric chromosome is considered a structural rearrangement, or abnormality, in the chromosome. It can arise through various mechanisms, such as chromosomal translocation or chromosomal breakage and fusion events.
Dicentric chromosomes pose significant challenges during cell division as they result in an unbalanced distribution of genetic material. This can disrupt normal cellular processes and may lead to cell death or the formation of abnormal cells that could have serious implications for an organism's health.
Researchers often study dicentric chromosomes to gain a better understanding of the mechanisms of chromosomal instability and the consequences of such aberrations. Understanding dicentric chromosomes is also relevant in the context of cancer research, as chromosomal abnormalities, including dicentric chromosomes, are frequently observed in tumor cells.
In summary, dicentric chromosomes are abnormal chromosomes that possess two centromeres instead of the usual one. These structural rearrangements are of interest to scientists due to their impact on cell division and genetic stability.
Common Misspellings for DICENTRIC
Etymology of DICENTRIC
The word "dicentric" is derived from two roots: "di-" and "centric".
The prefix "di-" originates from the Greek word "dis", meaning "two" or "twice". It indicates double, dual, or twice. In this case, it signifies the presence of two.
The term "centric" comes from the Latin word "centrum", which means "center". It is associated with words related to centers, central positions, or focus.
Therefore, "dicentric" combines these two elements to describe something that has two centers or foci. It is widely used in genetics and refers to a chromosome abnormality where a chromosome possesses two centromeres.
