Comparative Chromosome Maps of Neotropical Rodents Necromys lasiurus and Thaptomys nigrita (Cricetidae) Established by ZOO-FISH [PDF]
, 2011 This work presents chromosome homology maps between Mus musculus (MMU) and 2 South American rodent species from the Cricetidae group: Necromys lasiurus (NLA, 2n = 34) and Thaptomys nigrita (TNI, 2n = 52), established by ZOO-FISH using mouse chromosome ...

Acquired abnormalities of chromosome 21 in acute lymphoblastic leukaemia
, 2008 The intrachromosomal amplification of chromosome 21 (iAMP21) was identifiedas a novel and prognositically important acquired chromosomal abnormality inchildhood acute lymphoblastic leukaemia (ALL).

Cell Reports, 2016 Smc/ScpAB promotes chromosome segregation in prokaryotes, presumably by compacting and resolving nascent sister chromosomes. The underlying mechanisms, however, are poorly understood.

Scientific Reports, 2022 Homology-directed repair-mediated knock-in (HDR-KI) in combination with CRISPR-Cas9-mediated double strand break (DSB) leads to high frequency of site-specific HDR-KI. While this characteristic is advantageous for generating genetically modified cellular

Centromere function in asymmetric cell division in Drosophila female and male germline stem cells
Open Biology, 2021 The centromere is the constricted chromosomal region required for the correct separation of the genetic material at cell division. The kinetochore protein complex assembles at the centromere and captures microtubules emanating from the centrosome to ...

B Chromosomes – A Matter of Chromosome Drive [PDF]
Frontiers in Plant Science, 2017 B chromosomes are supernumerary chromosomes which are often preferentially inherited, deviating from usual Mendelian segregation. The balance between the so-called chromosome drive and the negative effects that the presence of Bs applies on the fitness of their host determines the frequency of Bs in a particular population.

‘Guide and Prejudice’— How Argonautes recognize targets across domains of life
FEBS Letters, EarlyView.Argonaute proteins use short nucleic‐acid guides to locate and regulate specific targets across all domains of life. Despite striking diversity—from human gene silencing to bacterial immune defence—all Argonautes share a conserved three‐stage recognition logic: guide‐directed sampling, progressive target pairing with a conformational checkpoint and ...

Induction of chromosome shattering by ultraviolet light and caffeine: The influence of different distributions of photolesions [PDF]
, 1986 Cells of synchonized and of asynchronously growing cultures of a V79 Chinese hamster line were microirradiated with a low poweer laser-UV-microbeam of wavelength 257 nm.

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Differences of size and shape of active and inactive X-chromosome domains in human amniotic fluid cell nuclei [PDF]
, 1993 It is a widely held belief that the inactive X-chromosome (Xi) in female cell nuclei is strongly condensed as compared to the largely decondensed active X-chromosome (Xa).
