Eukaryotic Chromosomal Structure and Compaction If the DNA from all 46 chromosomes in a human cell nucleus was laid out end to end, it would measure approximately two meters; however, its diameter would be only 2 nm. Considering that the size of a typical human cell is about 10 µm (100...
Fig. 1: Rye (‘Lo7’) genome composition and structure over chromosomes 1R to 7R. Twin vertical gray lines in each chromosome denote the boundaries of the pericentromeric low-collinearity regions for each chromosome. a, Genetic map positions of markers used in assembly. Scaffold boundaries marked...
a structure that pulls the chromatids to opposite ends of the cell). During the middle stage in cell division, the centromere duplicates, and thechromatidpair separates; each chromatid becomes a separate chromosome at this point. The cell divides, and both of the daughter cells have a complete...
Chromosomal segregation errors result in aneuploidy, an imbalance in the amount of genetic content that can be at the level of an entire chromosome or only a segment (Pfau & Amon, 2012). From:Current Topics in Developmental Biology,2023 ...
“the modern view states that Bs are enriched with genes for many significantbiological functions, including but not limited to the interesting set of genes related to cell cycle andchromosome structure. Furthermore, the presence of Bs could favor genomic rearrangements and influence the nuclear envir...
Suncus etruscus is one of the world’s smallest mammals, with an average body mass of about 2 grams. The Etruscan shrew’s small body is accompanied by a very high energy demand and numerous metabolic adaptations. Here we report a chromosome-level genome

Structure and evolution of the Forsythieae genome elucidated by chromosome-level genome comparison of Abeliophyllum distichum and Forsythia ovata (Oleaceae)Biological SciencesGeneticsAbeliophyllum distichum and Forsythia ovata are two closely related ornamental species of the tribe Forsythieae (Oleace...
Analysis of structural variation elucidated a repetitive structure of theccd1gene, which, in A188, consists of 13 copies. The high copy number ofccd1corresponds to the high expression level ofccd1, which was previously observed and presumably leads to a high activity of the carotenoid cleavage ...
Chromosome-level haplotype-resolved genome assembly is an important resource in molecular biology. However, current de novo haplotype assemblers require parental data or reference genomes and often fail to provide chromosome-level results. We present GreenHill, a novel scaffolding and phasing tool that ...
