A group of Chinese scientists has created powerful new tools that allow them to edit large chunks of DNA with incredible ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a ...

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

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

Small DNA loops regulate chromosome functions However, compaction isn’t enough. Cells also need to regulate the chromosome structure to enable its function. For example, when genetic information needs ...

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, ...

Scientists at the Center for Cell Dynamics, School of Biological and Behavioral Sciences, Queen Mary University of London, in ...

To turn genes off and on, cells use Structural Maintenance of Chromosomes (SMC) motors that act like switches to connect different parts of DNA,” first author Roman Barth, PhD, explained.

In cancer cells, whole genome duplication followed by haphazard chromosome loss allows tumour cells to accumulate genes that help them outgrow healthy cells. “When a cell makes a decision to divide it ...

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 protein found in our cells has emerged as a secret weapon against biological aging, acting like a glue to repair damaged DNA and ward off neurological degeneration including that seen in motor ...
