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.
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 ...
Karyotypes describe the chromosome count of an organism and what these chromosomes look like under a light microscope. Attention is paid to their length, the position of the centromeres, banding pattern, any differences between the sex chromosomes, and any other physical characteristics. [3]
Such changes may involve several different classes of events, like deletions, duplications, inversions, and translocations. Usually, these events are caused by a breakage in the DNA double helices at two different locations, followed by a rejoining of the broken ends to produce a new chromosomal arrangement of genes , different from the gene ...
Twin-arginine translocation pathway, a protein export pathway found in plants, bacteria, and archaea; Translocation (botany), transport of nutrients through phloem; Protein translocation, also called protein targeting, a process in protein biosynthesis; Species translocation, movement of a species, by people, from one area to another
This transport process is called translocation. [2] In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Ancient Greek word φλοιός (phloiós), meaning "bark". [3] [4] The term was introduced by Carl Nägeli in 1858. [5] [6] Different types of phloem can be distinguished. The early phloem formed in the ...
Translocation can be an effective management strategy and important topic in conservation biology, but despite their popularity, translocations are a high‐cost endeavor with a history of failures. [ 3 ] [ 4 ] It may decrease the risk of extinction by increasing the range of a species, augmenting the numbers in a critical population, or ...
If translocation occurs 3’-5’ the helicase is type A; if translocation occurs 5’-3’ it is type B. [26] Superfamily 1 (SF1): This superfamily can be further subdivided into SF1A and SF1B helicases. [26] In this group helicases can have either 3’-5’ (SF1A subfamily) or 5’-3’(SF1B subfamily) translocation polarity.
