The grafting is a horticultural technique that enables us to place a stem of a desired plant into another, more adequate already developed root system. This is done by cutting a branch from the already established plant, on the place of the precisely made cut we joint the desired stem, and then joint them together, be it with wax, mud, or a sellotape. The stem that has been placed on the established plant will be able to get the nutrients from it in this manner and become part of it, but it will produce different fruits from the established plant, it will produce its own fruits. This technique of course works only on plants that are more closely related and belong to the same family.
DNA replication is the process by which a molecule of DNA is duplicated. When a cell divides, it must first duplicate its genome so that each daughter cell winds up with a complete set of chromosomes.
