To prepare the 46 chromosomes of a human cell for transport to the daughter cells during cell division, each chromosome forms a compact X-shaped structure with two rod-like copies. How the cell ...

Chromosomes can be considered as self-organized liquid crystals Nucleosomes are repetitive building blocks introduced in the monotonous linear structure of double-helical DNA.

DNA holds our genetic blueprints, but its cousin, RNA, conducts our daily lives I n 1957, just four years after Francis Crick ...

One of the challenges of working with ancient DNA samples is that damage accumulates over time, breaking up the structure of the double helix into ever smaller fragments. In the samples we've ...

Cells also need to regulate the chromosome structure to enable its function. For example, when genetic information needs to be accessed, the DNA is locally read off.

Scientists found a key difference in how human and mosquito DNA organizes into chromosomes then figured out how to morph them back and forth.

The structure of how DNA is stored in archaea makes a significant difference to how quickly it evolves, according to a new study by Indiana University researchers.

However, a puzzle still remained. How was it possible that DNA fragments of ancient chromosomes survived for over 50,000 years with their three-dimensional structure intact?

Unusual chromosomal structure or variable distribution of chromosomes can result in physical and cognitive differences.‌ Trisomy. Sometimes, you can have an extra chromosome.

The first end-to-end (‘telomere-to-telomere’) completely gapless DNA sequence of a human chromosome is a major milestone for genomics research.
