Extensive DNA end processing by exo1 and sgs1 inhibits break-induced replication.
Homology-dependent repair of DNA double-strand breaks (DSBs) by gene conversion involves short tracts of DNA synthesis and limited loss of heterozygosity (LOH).

On a break with the X: the role of repair of double-stranded DNA breaks in X-linked disease [PDF]
The problem of managing free reactive DNA ends in eukaryotic cells has resulted in the development of a number of mechanisms in order to ensure that free ends are rendered non-reactive, or that the double-strand DNA breaks generating the free ends are ...

Autopolyploidy and allopolyploidy may represent an evolutionary advantage and are more common in plants than assumed. However, less attention has been paid to autopolyploidy than to allopolyploidy, and its evolutionary consequences are largely unclear ...

Analysis of chromosome positions in the interphase nucleus of Chinese hamster cells by laser-UV-microirradiation experiments [PDF]
Unsynchronized cells of an essentially diploid strain of female Chinese hamster cells derived from lung tissue (CHL) were laser-UV-microirradiated (=257 nm) in the nucleus either at its central part or at its periphery.

The Attraction between Homologous Chromosomes [PDF]
IT has been shown that the chromosomes of Datura (American Naturalist, vol. 56, pp. 339–346, 1922), Hyacinthus (Genetics, vol. 10, pp. 59–71, 1925) and Uvularia (Journal of Genetics, in press), for example, are combined side by side, and end to end, at the reduction division.

Meiotic cohesin SMC1β provides prophase I centromeric cohesion and is required for multiple synapsis-associated functions. [PDF]
Cohesin subunit SMC1β is specific and essential for meiosis. Previous studies showed functions of SMC1β in determining the axis-loop structure of synaptonemal complexes (SCs), in providing sister chromatid cohesion (SCC) in metaphase I and thereafter, in

Genetic Requirements for Intra-Chromosomal Deletions [PDF]
Chromosomal deletions are one of the most dangerous types of DNA damage and often arise as a result of inappropriately repaired DNA double strand breaks (DSB).

Ultrastructural analysis of chromatin in meiosis I plus II of rye (Secale cereale L.) [PDF]
Scanning electron microscopy (SEM) proves to be an appropriate technique for imaging chromatin organization in meiosis I and II of rye (Secale cereale) down to a resolution of a few nanometers.

Optimal Haplotype Assembly from High-Throughput Mate-Pair Reads
Humans have $23$ pairs of homologous chromosomes. The homologous pairs are almost identical pairs of chromosomes. For the most part, differences in homologous chromosome occur at certain documented positions called single nucleotide polymorphisms (SNPs).

Distribution of chromosome 18 and X centric heterochromatin in the interphase nucleus of cultured human cells [PDF]
In situ hybridization of human chromosome 18 and X-specific alphoid DNA-probes was performed in combination with three dimensional (3D) and two dimensional (2D) image analysis to study the interphase distribution of the centric heterochromatin (18c and ...
