Parents pass genes along to their offspring traits that equip them for life. In recent years, research has shown that the reality is much more complex and that parents endow much more than just genes. A new study in Cell ...
Scientists have identified a protein in fruit flies that can be targeted to reverse the effects of disease-causing mutations in mitochondrial genes. The discovery could provide clues about how to counteract human mitochondrial ...
Researchers at the Centro Nacional de Investigadores Cardiovasculares (CNIC) have established the dynamics of the transfer of mitochondrial DNA from mothers to their offspring. The study is published today in Cell Metabolism.
Researchers are a step closer to solving the puzzle of why older male sparrows are more successful at mating and producing chicks.
You might know that our lungs are lined with hair-like projections called motile cilia. These are tiny microtubule structures that appear on the surface of some cells or tissues. They can be found lining your nose and respiratory ...
Within hours after fertilization, a unique genome forms from chromosomes contributed by the egg and sperm. However, this new genome is initially inactive and must be "awakened" to begin the transcription of its DNA and start ...
The presence of a rival male affects sperm quality, according to a research study led by the University of Alicante and the University of Upsala (Sweden). The work was carried out with adult zebrafish (Danio rerio) and reveals ...
Pathological infertility is a condition affecting roughly 7 percent of human males, and among those afflicted, 10 to 15 percent are thought to have a genetic cause. However, pinpointing the precise genes responsible for the ...
From fathers to children, the delivery of hereditary information requires the careful packing of DNA in sperm. But just how nature packages this DNA to prepare offspring isn't clear. Using new technology to reveal the 3-D ...
When potential DNA evidence—say, from a sexual assault case—is submitted to a forensic lab for analysis, the scientists are often faced with the time-consuming challenge of sorting out which DNA profile came from the ...
