Here is a link from the Technology Cooperation Office, situated in Iran of all places. It's an English document titled "The legal implications of self-replicating technology". It is a lengthy piece, and even discusses missions into outer space and the implications nanotechnology has there. The website also has a number of links to other websites that discuss replication and nanotechnology. Very interesting to note where this article is coming from, and the detail with which the material is presented:

This comes from the website of the island one society, a society of "future space colonists" as they call themselves. The site is somewhat informal, but does have links to real material. The article below (properly referenced) briefly discusses a NASA idea about self assembling and self-replicating solar canopies for future space stations. The underlying idea consists of robots trained to put together these solar cell canopies, but they would also put together potential space habitats. These would become self-powering and self-replicating lunar habitats.

Mycoplasma are the smallest and simplest self-replicating bacteria. They have no cells walls, are extremely efficient and effective, and cause mass infections which are difficult to cure or overcome. They reproduce by binary fission, which usually starts with DNA replication, but in their case cytoplasmic division lags behind genome replication, and it is not uncommon to see multinuclear filaments. The link, description, and pictures are below.
