New insights in the regulation of genetic information exchange
Within every cell in our body, our DNA is tightly bundled with proteins to form structures known as chromosomes. The commonly known shape of a chromosome relates to an X-shaped appearance in many organisms. The formation of the X-shaped chromosome results from a close connection at a site called the centromere. This centromere acts as a link between the sister chromatids, the identical copies that are created during DNA replication.
