In early cytological studies chromatids of metaphase chromosomes were suggested to coil into a spiral called chromonema. This assumption was recently supported by chromosomce conformation capture ...

The cohesin protein complex is best known for its role in sister chromatid cohesion, which is crucial for accurate chromosome segregation. Mutations in cohesin proteins or their regulators have been ...

explain the difference between genetics and epigenetics. For students to grasp the basics of epigenetics, they will need an understanding of DNA and its structural chemistry in the chromosome.

In the cell, chromosomal DNA is wrapped around protein complexes in a structure often described as “beads on a string” (Figure 1). Each bead—called a nucleosome—contains roughly 140 base-pairs (bp) of ...

Among scientists, it is widely accepted that the structure of genomes largely controls their transcriptional activity within the cell. Structural features known as chromatin are responsible for this ...

Chromosomes are a highly condensed form of DNA and are crucial for cell division. During mitosis, chromosomes ensure that the genetic material is equally divided among the daughter cells.

The iconic X-shaped organization of metaphase chromosomes is frequently presented in textbooks and other media. The drawings explain in captivating manner that the majority of genetic information is ...
