Birth, expansion, and death of VCY-containing palindromes on the human Y chromosome

Genome Biology, 2019
Background Large palindromes (inverted repeats) make up substantial proportions of mammalian sex chromosomes, often contain genes, and have high rates of structural variation arising via ectopic recombination.

X-linked palindromic gene families 4930567H17Rik and Mageb5 are dispensable for male mouse fertility

Scientific Reports, 2022
Mammalian sex chromosomes are enriched for large, nearly-identical, palindromic sequences harboring genes expressed predominately in testicular germ cells.

GC-biased gene conversion in X-chromosome palindromes conserved in human, chimpanzee, and rhesus macaque

G3: Genes, Genomes, Genetics, 2021
Gene conversion is GC-biased across a wide range of taxa. Large palindromes on mammalian sex chromosomes undergo frequent gene conversion that maintains arm-to-arm sequence identity greater than 99%, which may increase their susceptibility to the effects

A perfect palindrome in the Escherichia coli chromosome forms DNA hairpins on both leading- and lagging-strands

Nucleic Acids Research, 2014
DNA palindromes are hotspots for DNA double strand breaks, inverted duplications and intra-chromosomal translocations in a wide spectrum of organisms from bacteria to humans.

Whole Genome Sequence Analysis of Mutations Accumulated in rad27Δ Yeast Strains with Defects in the Processing of Okazaki Fragments Indicates Template-Switching Events

G3: Genes, Genomes, Genetics, 2017
Okazaki fragments that are formed during lagging strand DNA synthesis include an initiating primer consisting of both RNA and DNA. The RNA fragment must be removed before the fragments are joined. In Saccharomyces cerevisiae, a key player in this process

Human AZFb deletions cause distinct testicular pathologies depending on their extensions in Yq11 and the Y haplogroup: new cases and review of literature

Cell & Bioscience, 2021
Genomic AZFb deletions in Yq11 coined “classical” (i.e. length of Y DNA deletion: 6.23 Mb) are associated with meiotic arrest (MA) of patient spermatogenesis, i.e., absence of any postmeiotic germ cells.

A Compression Algorithm for DNA Palindrome Compression Technique [PDF]

ITM Web of Conferences, 2020
Data Compression in Cryptography is one of the interesting research topic. The compression process reduces the amount of transferring data as well as storage space which in turn effects the usage of bandwidth.

Palindromic richness

European Journal of Combinatorics, 2009
In this paper, we study combinatorial and structural properties of a new class of finite and infinite words that are 'rich' in palindromes in the utmost sense. A characteristic property of so-called "rich words" is that all complete returns to any palindromic factor are themselves palindromes.

In girum imus nocte et consumimur igni. L’étendard de Guy Debord

Cahiers de Narratologie, 2009
Vingt et un ans après le Rapport sur la construction des situations de 1957, qu’on peut considérer comme le manifeste fondateur de l'Internationale Situationniste, Guy Debord, « se disant cinéaste », a tourné en 1978 son dernier long métrage, In girum ...

Myc oncogene-induced genomic instability: DNA palindromes in bursal lymphomagenesis. [PDF]

PLoS Genetics, 2008
Genetic instability plays a key role in the formation of naturally occurring cancer. The formation of long DNA palindromes is a rate-limiting step in gene amplification, a common form of tumor-associated genetic instability.
