Graphic Organizer

Changing DNA _______________ is a method used to produce new forms of DNA. In short words, changing DNA can lead to developing new organisms.

Gene engineering One method of genetic engineering is called ______________ which is a process where a piece of DNA is transferred to the DNA of another organism.

Steps in gene splicing are: 1. a piece of DNA is opened with special chemicals called enzymes 2. a new gene from another DNA is spliced or added into the DNA 3. DNA is closed

Gene splicing 1. a piece of DNA is opened with special chemicals called enzymes 2. a new gene from another DNA is spliced or added into the DNA 3. DNA is closed
