Sister Chromatids

Identical copies of a chromosome, connected by a centromere, formed during DNA replication and present until they are separated into two daughter cells during cell division.

Cohesin Proteins

Proteins that hold sister chromatids together, ensuring they are correctly segregated during cell division.

Ionic Bonding
