C BANDING Meaning and
Definition
-
C banding, also known as constitutive heterochromatin banding, is a cytogenetic technique used to identify and visualize chromosomal regions that contain highly repetitive DNA sequences. This technique involves treating chromosomes with chemical agents, such as barium hydroxide or acridine orange, which selectively stain regions rich in constitutive heterochromatin.
Constitutive heterochromatin refers to the tightly packed and transcriptionally inactive regions of DNA found near the centromeres and telomeres of chromosomes. These regions typically consist of repetitive DNA sequences, such as satellite DNA. By staining these regions using the C banding technique, researchers can distinguish them from the gene-rich euchromatic regions of the chromosomes.
The C banding technique is particularly useful in studying chromosomal rearrangements, such as translocations or inversions, as it helps identify and map specific heterochromatic regions that may be involved in these rearrangements. It can provide important diagnostic information for genetic disorders caused by chromosomal abnormalities, as well as aid in the identification of evolutionary changes in the karyotypes of different species.
C banding is commonly used in conjunction with other cytogenetic techniques, such as G banding, to provide a comprehensive view of the chromosomal structure and organization. It allows for the precise identification and characterization of heterochromatic regions within the genome, providing valuable insights into chromosomal dynamics and gene expression regulation.

Etymology of C BANDING
The etymology of the term "C banding" can be traced back to its use in cytogenetics, a field of biology that studies chromosomes and their structure. "C banding" refers to a technique called centromere banding, which helps identify and distinguish individual chromosomes.
The "C" in "C banding" stands for constitutive heterochromatin. Constitutive heterochromatin refers to a condensed region of DNA that remains permanently coiled and is typically found near the centromere of a chromosome. This region appears darkly stained when subjected to certain staining techniques, hence the term "banding".
So, "C banding" basically refers to the banding patterns observed in the constitutive heterochromatin of chromosomes when this technique is employed.
