Microbes Genetically Fit to Withstand Extreme Environmental Conditions

This article is about living organisms as small as microbes living beneath the ice layer in Antarctica. The article talks about enzymes and proteins in which are genetically adapted to maintain life in extreme temperatures in deep sea vents. The article discusses how flexible the ability of the enzymes and proteins must be to physically adapt to these conditions. Scientists in this article experimented by changing DNA sequences of these microbes changes their ability to withstand different extreme conditions and temperatures. Extremophiles like this microbes ultimately behave in the same ways when their genetic make up is altered from scientific mutation.

This article skewed my attention because I have not learned about much life in Antarctica due to that fact that it is below 0 degrees, which is unlivable for most organisms. I learned a fascinating technique of switching DNA sequence in an enzyme or protein's DNA can change an organisms optimal preference for environmental survival. The conceptualization of scientifically mutating an organism via science methods can change an organism's optimal environmental preference is extraordinary. This relates to genetics because DNA sequences are being altered for the study of extremophiles and their environmental behaviors. This research would particularly interest a marine science major or anyone interested in the genetics of microbial organisms.
