Using transgenesis to genetically modify animals has spawned a new division of using exogenous DNA to modify sperm cells. Epididymal sperm cells were shown to react to exogenous nucleic acids, allowing for DNA to reversibly bind to the spermatozoa through ionic interactions.
Transgenesis is being employed to genetically alter animals, which has resulted in a new area of research focusing on modifying sperm cells with exogenous DNA. It was discovered that epididymal sperm cells react to exogenous nucleic acids, enabling the reversible binding of DNA through ionic interactions.
