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 ...

A team of Chinese researchers led by Prof. GAO Caixia from the Institute of Genetics and Developmental Biology of the Chinese ...

The human genetic blueprint is deceptively simple. Our genes are tightly wound into 46 X-shaped structures called chromosomes. Crafted by evolution, they carry DNA and replicate when cells divide, ...

The multilamellar structure of DNA proposed by researchers is self-consistent and compatible with the structural and functional properties of chromosomes Date: September 14, 2024 Source: ...

Chromosomes are the tiny storage boxes that hold our DNA. Since each cell has about six feet of DNA packed inside it, it must be folded up tightly to fit.

The first step in DNA replication requires the assembly of a group of proteins called the Origin Recognition Complex (ORC). Researchers have determined how the ORC assembles during the cell ...

When cells prepare to divide, their DNA is tightly wound around proteins to form chromosomes that provide structure and support for genetic material.

A cell’s complete genetic blueprint, or genome, is densely packed into chromosomes, condensing meters of DNA into a minuscule cellular vessel only micrometers wide (SN: 8/24/15).

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot.
