Vibrio cholerae presents a unique model of bacterial genome organisation through its bipartite genome, comprising two distinct chromosomes that replicate in a carefully orchestrated manner. The ...
New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once thought. Half a century ago, scientists Jim Watson and Alexey Olovnikov ...
The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...
During the replication of the bacterial chromosome, genes close to the replication start point (red) exist in multiple copies, while genes close to the endpoint do not (blue). At faster growth, this ...
Every person starts as just one fertilized egg. By adulthood, that single cell has turned into roughly 37 trillion cells, many of which keep dividing to create the same amount of fresh human cells ...
As cells divide, they must copy all of their chromosomes once and only once, or chaos would ensue. How do they do it? By Amber Dance/Knowable Magazine Published Jul 7, 2023 6:00 PM EDT This article ...
Agrobacterium tumefaciens magnified 15,000 times in an image captured earlier this year with a scanning electron microscope at Iowa State University's Roy J. Carver High Resolution Microscopy Facility ...
A new study from Weill Cornell Medicine provides insights into how cells maintain the tiny end caps of chromosomes as they divide, a key process in keeping cells healthy. Using yeast, the researchers ...
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 ...
