Scientists have uncovered how brewer’s yeast developed its unusually tiny centromeres, the DNA regions that guide chromosome ...

Human disease including cancer arises from disfunction of essential processes within a cell. One essential cellular process is the copying of the genomic DNA—the road map of cells—followed by ...

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 ...

Cell division is one of the most thoroughly studied processes in biology, yet many of its details remain mysterious. A century-old puzzle surrounding the "crown" of cell division—the kinetochore ...

The biological factory that produces reproductive cells has a robust quality control system to identify and eliminate eggs with chromosomal abnormalities. For years, cell biologists have sought to ...

Matthew Miller, Ph.D., an assistant professor of biochemistry at University of Utah Health, was named as a 2022 Pew Scholar for his exploration of the cellular machines that help accurately divide and ...

Thousands of our cells successfully divide every day. They replicate their DNA and then separate so that each of the new cells has the same complement of chromosomes. If the process goes wrong and ...

Researchers for the first time have successfully fused two chromosomes in mice and shown that the new karyotype can be transmitted to offspring. The researchers used a strategy that involved haploid ...
