Question

) Assume that you are employed as a developmental biologist at NASA and the first returning mars explorer was found to have a small organism from mars onboard. The organism had the usual head-tail axis as well as dorsal-ventral polarity and what appeared to have right-left asymmetry. However upon analysis it was found to be composed of silicon based compounds and had no DNA, RNA or proteins at all. Discuss reasons why this organism would have similar developmental controls to those of earth’s carbon-based life and also discuss the opposing view as to why it would not.

Answer 1

My assumptions are given below:-

As mentioned above, the organism is found from Mars. The living habitat of mars is entirely different when it compared with the earth's habitat.The reasons why this organism would have similar developmental controls to those of earth's life are this organism have similar morphological characteristics with earth's organisms. Because this organism have usual head-tail axis as well as dorsal-ventral polarity and have right-left asymmetry.

This organism had no DNA,RNA or any protein and it is composed with silica. So it is not adapted to the carbon life of earth.
