Please help me with this question (4 parts). It's chemical biology related
Secret government files are uncovered that reveal the discovery of life on Mars!Martian organisms have DNA similar to Earth (Terran) DNA, but with a differentset of bases, shown below. The bases are uniquely Martian.NHNNHHNRHNRNH 2ofCAZCma. Physical studies of Martian DNA reveal a double helix, suggesting the presenceof paired bases. Draw the most likely base pairs (1 and 2) on Mars and justifyyour answer. (R = site of attachment to ribose sugar)b. Scientists attempt to interpret the Martian genetic code by first transforming it intoa Terran counterpart using PCR. DNA polymerase is able to "read" MartianDNA, but the scientists find that only some of the Martian bases form stable pairswith the Terran ones. Please draw the potential base pairs and comment ontheir stability.c. Attempts to culture Martian organisms on Earth fail; apparently, Martian DNA isstable at the colder temperatures on Mars but sometimes denatures at thewarmer temperatures of Earth. Explain why Martian duplex DNA could be lessstable than Terran duplex DNA.d. If you attempted to isolate a Martian DNA gene using PCR, how would the typical"melt" and "anneal" temperatures be affected if there was a preponderance ofbase pair 1 (from a)? What about base pair 2 (from a)?
