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 ...

Cells use many complex genetic repair backup systems to fix DNA damage and remain healthy throughout their lives.

Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of ...

Scientists report adaptive divergence in cryptic color pattern is underlain by two distinct, complex chromosomal rearrangements, where millions of bases of DNA were flipped backwards and moved from ...

DNA strand displacement circuits are inching closer to becoming cellular machines. Scientists are finding ways to make these ...

A new study has shown how chromosomes change shape during cell division. Certain protein complexes help fold DNA into overlapping loops that repel each other, which then stack to create a rod-like ...

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 ...

When even one tiny section of a person’s genetic code becomes mutated or modified, cells can begin to act out of ...

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 ...

For chromosomes to form the iconic X-shape that ensures the accurate passing of genetic information during cell division, a ...
