Question

If your goal is to characterize the ET polyurethane-degrading microbe (ETPUM), whose results are more informative: yours or your boss s? Why? What do your results indicate about the nature of this microbe? Does its biochemical composition most closely resemble that of a prokaryote or a eukaryote? Gram-positive or Gram-negative? Do you agree with your boss conclusion that the ETPUM is a prokaryotic-eukaryotic hybrid? Why or why not?

Boss's Sample Your Sample 80 S Ribosomes 70 S Ribosomes Circular DNA Linear DNA RNA Phospholipid membranes containing electron transport oteins Peptidoglycan LPS Lipoteichoic Acid Elagellar basal body roteins Pilus Proteins Nuclear Pore Proteins Histone Proteins

Explanation / Answer

I would consider my sample and not the boss'. There are conflicting results in the boss' table. One example would be the presence of 70S and 80S ribosomes and the other would be the presence of both circular and linear DNA.

Its biochemical composition indicates that it is a prokaryote with 70S ribosomes and circular DNA. It is gram positive as seen in the absence of teichoic acid. Since teichoic acid is seen only in gram negative organisms we can confirm that this organism is gram positive.

It cannot be a prokaryotic eukaryotic hybrid because eukaryotic cells contain organelles and prokaryotic cells do not have organelles.Since the membrane contains electron transport proteins which is seen in mitochondria and chloroplast in eukaryotes, we can confirm that this is not a hybrid.
