Therefore, chromatin is further coiled into an even ... the DNA becomes highly compacted into the classic metaphase chromosomes that can be seen with a light microscope. Once a cell has divided ...
During interphase, individual chromosomes are not visible, and the chromatin appears diffuse and unorganized. Recent research suggests, however, that this is an oversimplification and that ...

Genes can now be studied by bending DNA strands with lightIn a groundbreaking study, scientists have discovered a way to manipulate the very fabric of life by using light to reshape ...
The largest of these loops results from the helical coiling of chromatin (the thick line in this illustration). This coiling causes the chromosome to resemble a spring. Chromatin refers to ...
Grappling motors bring distant segments of chromatin fibers together, creating long-range correlations that are needed to ...

Healthy breast cells can look like invasive cancer, complicating early diagnosisScientists found that healthy women can carry genetic changes in their breast cells that are thought to be characteristic of ...
The method, called ChIP–DIP (Chromatin ImmunoPrecipitation Done In Parallel), ...
In all cultures examined the chromosome number was predominantly ... Such a 2:1 male-female sex-chromatin ratio is consistent with the parthenogenetic origin of these tumors by autofertilization ...
We are interested in the mechanism of chromosome replication, a process that is highly conserved across eukaryotes and that involves the duplication of both the chromosomal DNA and its associated ...
This important study reveals a role for IκBα in the regulation of embryonic stem cell pluripotency. The solid data in mouse embryonic stem cells include separation of function mutations in IκBα to ...
This course provides and overview of epigenetic mechanisms, including DNA methylation, histone modifications, chromosome structure, and nuclear organization. We will discuss how molecules help ...
