NOVA scienceNOW: Artificial Life

|
|
Program Overview
|
|
|
Scientists discuss how they are attempting to construct simple life-forms in
the laboratory, and they describe the potential benefits of specifically
designed artificial life-forms.
This NOVA scienceNOW segment:
describes how scientists are trying to create tiny
life-forms—converting nonlife into self-sustaining, living creatures. notes that there has been no totally new life-form for about 3.5
billion years. discusses the requirements for life—a container; the ability to
grow or change using energy; the ability to reproduce; and for some, the
ability to evolve. shows how scientists combine the bases adenine, thymine, guanine, and
cytosine to make DNA that self-assembles into a gene that codes for something
specific, such as making bacteria glow green. points out that some people are concerned about laboratory-created life
and that others think it is important to proceed with the work because of its
potential good.
