According to a new study, children exposed to high levels of the common air pollutant naphthalene are at increased risk for chromosomal aberrations (CAs), which have been previously associated with cancer.

Besides the obvious differences between plants and animals, subtle ones lie concealed within the cell, even within the nucleus.

Cohesin is a ring-shaped protein complex involved in the spatial organization of the genome and in mitotic chromosome structure.

In today's society, kids already act and look older than they are. Recent research has proved that the DNA of 10-year-olds who have experienced violence at a young age are found to show wear and tear normally associated with aging.

Researchers have found that violence in the lives of children can cause changes in their DNA equivalent to seven to 10 years of premature aging. Scientists measured this cellular aging by studying the ends of children’s chromosomes, called telomeres.
