WebThe shorter arm of a chromosome is termed the p arm or p-arm, while the longer arm is the q arm or q-arm. The chromosomal locus of a typical gene, for example, might be written 3p22.1, where: 3 = chromosome 3 p = p-arm 22 = region 2, band 2 (read as "two, two", not "twenty-two") 1 = sub-band 1 WebIt is the constricted region from where chromosome's arms (chromatids) originate; a short arm (p arm) and a long arm (q arm). It is the link between two sister chromatids. Centromere gives the chromosome its unique shape that helps understand its structure and location of genes.
WebEach human chromosome has a short arm ("p" for "petit") and long arm ("q" for "queue"), separated by a centromere. The ends of the chromosome are called telomeres. Each chromosome arm is divided into regions, or cytogenetic bands, that can be seen using a microscope and special stains. WebMost of them show rearranged chromosomes, with a variable portion of the Y chromosome short arm—bearing the SRY gene—translocated to another chromosome. The most frequent occurrence is an X-Y translocation, consequent to an aberrant crossing-over during the father’s meiosis [ 51 ].
