When a woman becomes pregnant, the outcome of that pregnancy depends on many things - including a crucial event that happened ...

Chromosomes continuously develop their shape during cell divisions. Mitotic chromosomes gradually shorten and thicken. Longer ...

Penn biologists present new evidence on how telomere length is inherited in early embryos. Their findings open new avenues ...

Some genes just don’t play fair. Researchers have uncovered a ‘selfish’ X chromosome in the fruit fly Drosophila testacea that manages to distort inheritance in both sperm and eggs. “Researchers have ...

Starting as a single cell, organisms undergo millions of generations of divisions to ultimately generate the bones, heart, brain and other components that make up a living being. The mainspring within ...

A new application of the CRISPR/Cas molecular scissors promises progress in crop cultivation. Researchers have succeeded in modifying the sequence of genes on a chromosome using CRISPR/Cas. For the ...

The first theoretical model of condensin, a molecular machine involved in packing and unpacking chromosomes, accurately reproduces all known experiments with just two parameters. To scrunch a ...

A team of biologists has uncovered a mechanism that determines faithful inheritance of short chromosomes during the reproductive process. The discovery elucidates a key aspect of inheritance -- ...

An international research team has achieved a significant breakthrough in research into the reproduction of dogrose. The study, which has now been published in Nature, shows how differences in the ...

Bipolar affective disorder is a severe mood disorder that afflicts approximately 1% of the population worldwide. Twin and adoption studies have indicated that genetic factors contribute to the ...
