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.
Gene conversion is the process by which one DNA sequence replaces a homologous sequence such that the sequences become identical after the conversion. [1] Gene conversion can be either allelic, meaning that one allele of the same gene replaces another allele, or ectopic, meaning that one paralogous DNA sequence converts another.
Copy number variation was initially thought to occupy an extremely small and negligible portion of the genome through cytogenetic observations. [12] Copy number variations were generally associated only with small tandem repeats or specific genetic disorders, [13] therefore, copy number variations were initially only examined in terms of specific loci.
De novo sequence assembly may be applied with reads that are accurate enough. While, in practice, use of this method is limited by the length of sequence reads, long read based genome assemblies offer structural variation discovery for classes such as insertions that escape detection when using other methods.
Cre-Lox recombination is a site-specific recombinase technology, used to carry out deletions, insertions, translocations and inversions at specific sites in the DNA of cells. It allows the DNA modification to be targeted to a specific cell type or be triggered by a specific external stimulus. It is implemented both in eukaryotic and prokaryotic ...
The more similarity within the sequences, the more likely unequal crossing over will occur. [1] One of the sequences is thus lost and replaced with the duplication of another sequence. When two sequences are misaligned, unequal crossing over may create a tandem repeat on one chromosome and a deletion on the other.
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
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 ...
