Chromosomal reciprocal translocation of the 4th and 20th chromosome. In genetics, chromosome translocation is a phenomenon that results in unusual rearrangement of chromosomes. This includes balanced and unbalanced translocation, with two main types: reciprocal, and Robertsonian translocation.
Class 1 consists of GLUT 1-4 and 14, class 2 contains GLUT 5, 7, 9 and 11, and class 3 has GLUT 6, 8, 10, 12 and 13. Although there are some sequence differences between all GLUT proteins, they all have some basic structural components.
The translocon (also known as a translocator or translocation channel) is a complex of proteins associated with the translocation of polypeptides across membranes. [1] In eukaryotes the term translocon most commonly refers to the complex that transports nascent polypeptides with a targeting signal sequence into the interior (cisternal or lumenal) space of the endoplasmic reticulum (ER) from ...
Translocation may refer to: Chromosomal translocation, a chromosome abnormality caused by rearrangement of parts Robertsonian translocation, a chromosomal rearrangement in pairs 13, 14, 15, 21, and 22; Nonreciprocal translocation, transfer of genes from one chromosome to another; PEP group translocation, a method used by bacteria for sugar uptake
Satellite chromosomes or SAT-chromosomes are chromosomes that contain secondary constructs that serve as identification. They are observed in acrocentric chromosomes. In addition to the centromere, one or more secondary constrictions can be observed in some chromosomes at metaphase.
In a translocation heterozygote, the two haploid sets of chromosomes do not carry the same arrangement of genetic information. As a result, during prophase of the first meiotic division, the translocated chromosomes and their normal homologs assume a crosslike configuration in which four chromosomes, rather than the normal two, pair to achieve ...
For example, 46,XY,der(4)t(4;8)(p16;q22)t(4;9)(q31;q31) would refer to a derivative chromosome 4 which is the result of a translocation between the short arm of chromosome 4 at region 1, band 6 and the long arm of chromosome 8 at region 2, band 2, and a translocation between the long arm of chromosome 4 at region 3, band 1 and the long arm of ...
t(11;14) is a chromosomal translocation which essentially always involves the immunoglobulin heavy locus, also known as IGH in the q32 region of chromosome 14, as well as cyclin D1 which is located in the q13 of chromosome 11 . [2] Specifically, the translocation is at t(11;14)(q13;q32). [3] [4]
