Researchers uncover hidden DNA process safeguarding chromosomes, potentially explaining infertility, miscarriage, and Down syndrome

A hidden DNA process safeguarding chromosomes has been uncovered, potentially explaining infertility, miscarriage, and Down syndrome. Researchers identified protein networks that protect chromosome crossovers in eggs, preventing errors during cell division. This process is crucial for genetic stability across generations. The findings, based on yeast studies, have direct counterparts in humans and could advance understanding and treatment of human fertility issues.
