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’s chemical cousin, RNA, was the messenger that carries DNA instructions from the double helix in the cell’s nucleus to ...

Here, you will find information on the chemical structure of DNA; organization of DNA into chromosomes, genes, and gene families; the processes of DNA replication, transcription, and translation ...

DNA often experiences torsional stress inside living cells, whether through the packing of chromosomes in the nucleus or the ...

The three-dimensional organization of the chromosomes affects vital biological processes such as DNA replication and the differentiation of cells as embryos develop.

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.

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.

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 ...

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

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?
