Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of ...
A new study from Weill Cornell Medicine provides insights into how cells maintain the tiny end caps of chromosomes as they ...
Take the experiment that Bruce Nicklas designed to test Dietz's theory that chromosomes adopt bipolar orientations during metaphase of mitosis and meiosis because this orientation enables them to ...
How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? Histones are a family of small, positively charged proteins termed H1, H2A, H2B, H3, and H4 (Van Holde ...
The biological research of UC Santa Cruz’s Needhi Bhalla to determine the molecular motions at the heart of heredity has ...
For chromosomes to form the iconic X-shape that ensures the accurate passing of genetic information during cell division, a ...
To prepare the 46 chromosomes of a human cell for transport ... led by Andreas Brunner and recently published in the Journal of Cell Biology, shows that the nested loop mechanism is fundamental ...
They did so by studying extra-long chromosomes with two or more crossovers. The findings are published in the journal Current Biology. "Taking advantage of fusion chromosomes with multiple ...
Cells with an abnormal number of chromosomes consequently activate mechanisms to prevent their propagation. In a study published in Nature Cell Biology, scientists reveal how these chromosomal ...
For the first time, researchers have fused two mouse chromosomes together in vitro, resulting in living mice with new karyotypes. The new technique, detailed in a study published today (August 25) in ...
The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...
Now, researchers in New York have shown what shelterin protects chromosomes from—six different DNA repair systems, including two not previously known to attack telomeres. The study, published today ...
