A human cell undergoing cell division where the goal is to align duplicated chromosomes and deliver a perfect set to the two new “daughter cells.” Image courtesy Ben Black. HACs have wide potential ...

Earlier methods to synthesize HAC relied on linking shorter DNA constructs into a larger chromosome within the cell in a process called multimerization. However, the genetic fragments tended to ...

The images above depict artificially-derived neurons grown in petri dishes, with a human neuron shown on the left. Artificially-derived chimpanzee neurons grow only one or two neurites (connecting ...

For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...
