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).

New research into mitotic chromosomes has found that they are covered in a liquid-like coating that could allow them to ...

A human cell carries in its nucleus two meters of spiraling DNA, split up among the 46 slender, double-helical molecules that are its chromosomes. Most of the time, that DNA looks like a tangled ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes.

DNA molecules are long, string-like polymers storing the genetic information of life and, in a cell, are tightly packed into structures called chromosomes.

Cell division is the mechanism by which DNA is passed from one generation of cells to the next and ultimately, ... each of which contains the same number of chromosomes as the parent cell. ...

Earlier efforts to build human artificial chromosomes focused on these structures, extracting DNA letters that could express proteins inside human cells to anchor the chromosomes. However, these DNA ...

For this, the cell must duplicate its DNA – its genome – and segregate it equally into two new daughter cells. To prepare the 46 chromosomes of a human cell for transport to the daughter cells ...

Now, scientists at the Salk Institute have discovered a new characteristic of human cell division that may help explain how our DNA is organized in the nucleus as cells reproduce. They found that ...

New imaging tools reveal how within an hour of infection, the virus begins to alter our chromosomes to kick-start its own replication.

Chromosome 'anchors' organize DNA during cell division Salk discovery of new role for telomeres in cellular growth may shed light on aging and age-related diseases ...
