Explanation:

A bivalent refers to a chromosome complex that is formed by the pairing of two homologous chromosomes during the zygotene stage of prophase I of meiosis I. Therefore, there is a total of four chromatids in a bivalent. Each chromatid of a chromosome has one DNA helix. This makes a bivalent to have a total of 4 DNA helices (two in one homologous chromosome).
