Polymerase Chain Reaction (PCR) Archives

Flowchart of the experimental design. The DNA was extracted from C. antarcticus colonies and divided into two 1.5 mL Eppendorf tubes, one containing a Martian regolith analogue and the other without it. Both tubes were exposed to iron (Fe) ions to simulate environmental stress conditions similar to those experienced on Mars. After exposure, the extracted DNA was resuspended in nuclease-free water and quantified using spectrophotometry, achieving a final concentration of 0.1 ng/mL. Subsequently, the quantified DNA was subjected to amplification using two main techniques: PCR (Polymerase Chain Reaction) to produce multiple copies of the target DNA, and qPCR (quantitative PCR) to determine the exact amount of amplified DNA, monitoring the process in real time. -- Life
