How molecular clocks are refining human evolution's timeline

DNA holds the story of our ancestry – how we're related to the familiar faces at family reunions as well as more ancient affairs: how we're related to our closest nonhuman relatives, chimpanzees; how Homo sapiens mated ...

Unlocking crop diversity by manipulating plant sex

Researchers have discovered a key gene that influences genetic recombination during sexual reproduction in wild plant populations. Adding extra copies of this gene resulted in a massive boost to recombination and diversity ...

How breaks in DNA are repaired

A team of researchers from the biology department at TU Darmstadt has discovered that the processes for repairing DNA damage are far more complex than previously assumed. The ends of breaks in the double helix are not just ...

How does a honeybee queen avoid inbreeding in her colony?

Recombination, or crossing-over, occurs when sperm and egg cells are formed and segments of each chromosome pair are interchanged. This process plays an crucial role in the maintanance of genetic variation. Matthew Webster ...
