Condensin Ii Promotes The Formation Of Chromosome Territories By Inducing Axial Compaction Of Polyploid Interphase Chromosomes, Christopher R. R. Bauer, Tom A. Hartl, Giovanni Bosco
Condensin Ii Promotes The Formation Of Chromosome Territories By Inducing Axial Compaction Of Polyploid Interphase Chromosomes, Christopher R. R. Bauer, Tom A. Hartl, Giovanni Bosco
Dartmouth Scholarship
The eukaryotic nucleus is both spatially and functionally partitioned. This organization contributes to the maintenance, expression, and transmission of genetic information. Though our ability to probe the physical structure of the genome within the nucleus has improved substantially in recent years, relatively little is known about the factors that regulate its organization or the mechanisms through which specific organizational states are achieved. Here, we show that Drosophila melanogaster Condensin II induces axial compaction of interphase chromosomes, globally disrupts interchromosomal interactions, and promotes the dispersal of peri-centric heterochromatin. These Condensin II activities compartmentalize the nucleus into discrete chromosome territories and indicate …
Organization Of The Centromeric Satellite I Cluster And D21z1 Short Arm Junction Region Of Human Chromosome 21, Riddhi V. Patel
Organization Of The Centromeric Satellite I Cluster And D21z1 Short Arm Junction Region Of Human Chromosome 21, Riddhi V. Patel
Master's Theses
To study chromosomal segregation errors causing Down syndrome one needs a chromosome 21 (HC21) specific centromeric marker, which presently does not exist. Alphoid DNA is the only repetitive sequence at all human centromeres. The current map of HC21 has a gap in the p-arm alphoid (D21Z1) junction region and the centromeric satellite I (satI) sequence. This satellite I cluster was shown not to be a specific centromeric marker since it is also on HC13. There are actually multiple satI families on both HC13 and HC21. This project also filled the gap in the HC21map and characterized the D21Z1 p- arm …
