Samples of DNA squirted onto the exterior of a TEXUS-49 sounding - TopicsExpress



          

Samples of DNA squirted onto the exterior of a TEXUS-49 sounding rocket remained functional following a 13-minute suborbital spaceflight. We cannot say how these big chromosomal DNA molecules would react under the same conditions, and this should be investigated in a separate experiment, scientists reported. However, we speculate that small plasmid DNA molecules might be more resistant to re-entry conditions than chromosomal DNA, which is also packed with proteins. (Ed: So panspermia is looking like a really intriguing possibility, but we might also be carrying terrestrial DNA to wherever our space ships land)
