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 ...

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 ...

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 ...

Chromatin, the material that makes up chromosomes, is a complex structure where long strands of DNA are wrapped tightly around proteins. Despite its compact nature, chromatin must unfurl in ...

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 ...

This course provides and overview of epigenetic mechanisms, including DNA methylation, histone modifications, chromosome structure, and nuclear organization. We will discuss how molecules help ...

Most cancer cells have too many or too few chromosomes, distinguishing them ... called the assay for transposase-accessible chromatin sequencing (ATAC-seq), to look for any genetic anomalies ...

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 ...
