![]() ![]() It becomes a reference library of things that negatively impact the genome.Ĭas9 is a protein that specifically works with RNA to recognize DNA sequences. CRISPR is the area of DNA that stores information when the genome is fractured by something invasive like a virus or an environmental insult (radiation). The acronym stands for Clusters of Regularly Interspaced Short Palindromic Repeats and is embedded in DNA. For those who worry that CRISPR/Cas9 is something alien to our DNA, it is not. I have chosen one to highlight here to get you started. If you are not familiar with CRISPR/Cas9, a quick search on this blog site using the term “CRISPR” will yield a number of pertinent articles. The experiment, conducted in 2019, eventually led to a paper submitted for publication. The DNA was then examined for potential mutations. The experiment created breaks in the yeast DNA which were then repaired using CRISPR/Cas9 technology. That’s why in response to a 2018 NASA Genes in Space contest related to long-duration space flight, a team of four young high school students devised a yeast DNA experiment that moved from their science lab to the one onboard the International Space Station (ISS). ![]() NASA astronaut Nick Hague runs Genes in Space-6 experiment during Expedition 59 to explore how space radiation damages DNA and how cells repair that damage in microgravity.Ĭosmic rays and solar radiation represent a significant threat to the health of humans or any other species of animal or plant venturing into outer space beyond the protection of Earth’s magnetic field and atmosphere. ![]()
