(Phys.org) —The ability of a cell to move, replicate, and recast itself according to the needs of the organism which it serves, comes at it price. The extreme flexibility of cells takes its origin from the constant turnover ...
Basic biology textbooks may need a bit of revising now that biologists at UC San Diego have discovered a never-before-noticed component of our basic genetic material.

Every cell in our body has exactly the same DNA, yet every cell is different. A cell's identity is determined by the subset of genes that it activates. But how does a cell know which genes to turn off and which to turn on? ...

In the cells of palm trees, humans, and some single-celled microorganisms, DNA gets bent the same way. Now, by studying the 3-D structure of proteins bound to DNA in microbes called Archaea, University of Colorado Boulder ...

When stretched out, the genome of a single human cell can reach six feet. To package it all into a tiny nucleus, the DNA strand is tightly wrapped around a core of histone proteins in repeating units—each unit known ...

All the trillions of cells in our body share the same genetic information and are derived from a single, fertilized egg. When this initial cell multiplies during fetal development, its daughter cells become more and more ...
