CHROMOSOMAL ABERRATION Meaning and
Definition
-
Chromosomal aberration refers to any deviation or abnormality observed in the structure or number of chromosomes in a cell. Chromosomes are thread-like structures found inside the nucleus of a cell that carry genetic information in the form of DNA. They are responsible for determining various traits and characteristics in living organisms.
A chromosomal aberration can occur due to errors during cell division, such as non-disjunction or translocation, or due to exposure to certain environmental factors, such as radiation or chemicals. These abnormalities can result in genetic disorders or abnormalities in an individual.
Structural chromosomal aberrations involve alterations in the structure of a chromosome, such as deletions, duplications, inversions, or translocations. Deletions occur when a part of the chromosome is missing, while duplications occur when a segment is repeated. Inversions involve the reversal of a segment within a chromosome, and translocations occur when a part of one chromosome gets transferred to another chromosome.
Numerical chromosomal aberrations are characterized by changes in the number of chromosomes. This can include conditions such as aneuploidy, where there is an abnormal number of chromosomes, as well as polyploidy, where there are extra sets of chromosomes.
Chromosomal aberrations can lead to a range of genetic disorders, such as Down syndrome, Turner syndrome, Klinefelter syndrome, or chromosomal translocation disorders. Their impact can vary depending on the specific alteration, the number of chromosomes affected, and the genes involved. Diagnosis of chromosomal aberrations is often done through specialized tests, such as karyotyping or fluorescence in situ hybridization (FISH).

Etymology of CHROMOSOMAL ABERRATION
The word "chromosomal" comes from the Greek word "chroma", meaning "color", and the Latin word "chromos", meaning "chromosome". The term "aberration" comes from the Latin word "aberrare", meaning "to deviate" or "to go astray". Therefore, "chromosomal aberration" refers to a deviation or abnormality in the structure or number of chromosomes in a cell or organism.
