The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every ...

From 1 September, only those athletes who have passed the SRY gene test will be allowed to participate in women's ...

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

A new study by EMBL researchers has shown how chromosomes change shape during cell division. Certain protein complexes help fold DNA into overlapping loops that repel each other, which then stack ...

The activity of these "switches" is regulated by their methylation status, chemical marks that can be added to or removed ...

TIANJIN, July 16 (Xinhua) -- A Chinese research team has made a significant leap in the field of synthetic biology by precisely synthesizing and assembling large-scale human DNA and successfully ...

Each of our 46 chromosomes is composed of double-stranded DNA. During homologous recombination, sections around a double-strand break are cut away, and the ends of the broken DNA molecule invade the ...

Scientists have used gene editing to remove the extra chromosome causing Down syndrome in lab-grown cells. A major step ...

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 ...

DNA is a resolutely three-dimensional molecule. In animals and plants, long strands are coiled and folded into chromosomes, which store genetic information inside the nucleus of a body’s cells.
