Interface - The agreed upon way that a function is called. Example: The toaster, microwave oven, and blender in my home all have the same US 120 volt 60 Hertz interface. I can use any plug on the counter for any of them. Facade Pattern / Bridge Pattern - A go-between between 2 interfaces.
Germline Gene Transfer. Gene transfer represents a relatively new possibility for the treatment of rare genetic disorders and common multifactorial diseases by changing the expression of a person's genes. Typically gene transfer involves using a vector such as a virus to deliver a therapeutic gene to the appropriate target cells.
Horizontal gene transfer (HGT) or lateral gene transfer (LGT) is the movement of genetic material between unicellular and/or multicellular organisms other than by the (vertical) transmission of DNA from parent to offspring. HGT is an important factor in the evolution of many organisms.
