About this Book

The biological DNA contained in the sperm is formed by the process called gametogenesis. It consists of different phases after which male and female sex cells are formed. The structure of DNA provides a mechanism for inheritance. The conformation adopted by the DNA depends on the level of hydration, the sequence of the DNA, the amount and direction of the super-winding, the chemical modifications of the bases, the type and concentration of metal ions and the presence of polyamines in solution.
