A A new diploid cytotype of Agrimonia pilosa (Rosaceae)
Caryologia, 2020 A new diploid cytotype of Agrimonia pilosa Ledebour (Rosaceae) collected in China has been revealed. Karyotype formula is 2n = 2x = 16 = 14m + 2sm. Previously, chromosome numbers in A.

Karyotyping human chromosomes by optical and X-ray ptychography methods [PDF]
, 2014 Sorting and identifying chromosomes, a process known as karyotyping, is widely used to detect changes in chromosome shapes and gene positions. In a karyotype the chromosomes are identified by their size and therefore this process can be performed by ...

NOMENCLATURE FOR CENTROMERIC POSITION ON CHROMOSOMES
, 2009 N the inorphologic identification of chromosomes, the location of the I centromere is the most useful landmark, and one which is characterized by great constancy. It would seem that not much could be added to the definitions by E. B. WILSON (1928) of the

Proceedings of the National Academy of Sciences of the United States of America, 1988 A highly conserved repetitive DNA sequence, (TTAGGG)n, has been isolated from a human recombinant repetitive DNA library. Quantitative hybridization to chromosomes sorted by flow cytometry indicates that comparable amounts of this sequence are present on

Chromosomal rearrangements in cattle and pigs revealed by chromosome microdissection and chromosome painting [PDF]
Genetics Selection Evolution, 2003 A pericentric inversion of chromosome 4 in a boar, as well as a case of (2q-;5p+) translocation mosaicism in a bull were analysed by chromosome painting using probes generated by conventional microdissection. For the porcine inversion, probes specific for p arms and q arms were produced and hybridised simultaneously on metaphases of a heterozygote ...

Non-random chromosome positioning in mammalian sperm nuclei, with migration of the sex chromosomes during late spermatogenesis [PDF]
, 2005 Chromosomes are highly organized and compartmentalized in cell nuclei. The analysis of their position is a powerful way to monitor genome organization in different cell types and states.

DNA sequence of both chromosomes of the cholera pathogen Vibrio cholerae
Nature, 2000 Here we determine the complete genomic sequence of the Gram negative, γ-Proteobacterium Vibrio cholerae El Tor N16961 to be 4,033,460 base pairs (bp). The genome consists of two circular chromosomes of 2,961,146 bp and 1,072,314 bp that together encode 3,

Unscheduled DNA synthesis after partial UV irradiation of the cell nucleus [PDF]
, 1979 Cells of an euploid strain of the Chinese hamster synchronized in the G1 phase were microirradiated in the nucleus with a laser UV microbeam (λ = 257 nm) and pulse-labelled with [3H]thymidine. In autoradiographs of cells fixed immediately after the pulse
