Men Can Lose Their Y Chromosome With Age, And We Finally Know The Cost
(Cavan Images/Getty Images) The human Y chromosome is shrinking. In the next 5 million years or so, some geneticists think ...
In each cell of your body, DNA is stored in structures called chromosomes. When cells divide, these chromosomes are copied, ...
Researchers have just completed the first full sequence of a Y chromosome- what will we learn? The Telomere-to-Telomere (T2T) consortium, co-led by UC Santa Cruz Genomics Institute Associate Director ...
The initiation of chromosome replication is exquisitely regulated in both time and location. It has been estimated that there are 200-400 autosomal replication sequence elements (ARSs) in the yeast ...

It's tricky to make an exact copy of yourself. Or at least it is for cells undergoing mitosis, where cells replicate everything inside of them, including their neatly packaged DNA, then split in half.

Cells that double their DNA through failed division survive far better than those from botched chromosome splits, a clue to how some cancers take hold
Cells that acquire a doubled genome after a failed division step survive and proliferate far more effectively than cells left ...
Half a century ago, scientists Jim Watson and Alexey Olovnikov independently realized that there was a problem with how our DNA gets copied. A quirk of linear DNA replication dictated that telomeres ...
Top: Chromosome separate with functioning SMC in two models, line drawing and filled-space. The red and pink dots indicate, respectively, ori on each copy of DNA. Bottom: DNA separating without ...
