Computational biology played a crucial role in mapping the human genome, significantly speeding up a process that would have taken decades longer using traditional methods. elaborate
There are more bacteria in a single human mouth than there are people on Earth. elaborate
Some astrobiologists believe that life on other planets might be based on different elements than carbon, potentially silicon. elaborate
