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 ...

The biological research of UC Santa Cruz’s Needhi Bhalla to determine the molecular motions at the heart of heredity has yielded a new discovery: The proper transfer of genetic materials depends on ...

Mitosis is the main cell reproduction process in a living organism's tissues, and meiosis is the process that induces sex cell formation in the gonads of organisms that reproduce sexually. The Meiosin ...

Neurons result from a highly complex and unique series of cell divisions. For example, in fruit flies, the process starts with stem cells that divide into mother cells (progenitor cells), that then ...

Genes control this production process by telling the cells either to divide --and which particular type of cell to produce-- or to stop dividing. To this day, only a few of the genes that control this ...

An experimental study from researchers in the Perelman School of Medicine at the University of Pennsylvania links a specific procedure - embryo culture - that is part of the assisted reproduction ...
