The human genome is packaged into a set of chromosomes as in other eukaryotes. Chromosomes are thus the vehicles of inheritance as they contain virtually the entire cellular DNA with the exception of the small fraction present in the mitochondria. The structure, function, and behavior of chromosome...
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 level of the oxidative DNA damage and lipid peroxidation was evaluated using immunoperoxidase staining for 8-hydroxydeoxyguanosine (8-OHdG) and by ... A Yu,L Jiang,J Cao,... - 《Mutation Research》 被引量: 135发表: 2007年 Possible involvement of oxidative stress in trichloroethylene-indu...
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–d, Structure and sequence identity of the chimpanzee (H1) (a), chimpanzee (H2) (b), orangutan (c) and macaque (d) chromosome 8 centromeres. Each centromere has a mirrored organization consisting of four or five distinct evolutionary layers. The size of each centromeric region is consiste...
there was a high degree of collinearity betweenS. albumandS. yasiin both genes and genome structure (Supplementary Figs.11and12). We also found some 1:2, 2:2, 1:3, 2:3, and 3:3 relationships betweenS. albumandS. yasiin the collinear dot plot. It is well known that subfunctionalization...
Structure of the human Y chromosome. The Pseudo Autosomal Regions [PAR1 and PAR2] are located at the terminal ends of the Y chromosome. The green boxes show the genes encoded in these regions. Yp is the short arm of the Y chromosome and the genes within it are show in the peach box...
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 ...
a high-quality chromosome-level genome ofT. mongolicuswas generated. K-mer analysis revealed that the genome size ofT. mongolicuswas 559.25 Mb, with heterozygosity and repetitive sequences accounting for 1.99% and 57.64%, respectively (Table S1), indicating a complex genome structure in this species...
In a Fig. 2: Frequent chromosomal rearrangements across parrot genomes. Pairwise whole-genome alignments across eight chromosome-level assemblies of bird genomes. Each horizontal bar represents one chromosome, and chromosome IDs of chicken were labeled at the bottom; for parrot genomes some chromosomes...
