Why might the analysis of endosymbiotic bacterial genomes be misleading for understanding the minimal gene set?
A)They may have lost genes that would have been essential to early life-forms due to their reduced metabolic requirements.
B)They may have gained genes to be able to live within another organism.
C)They are bacteria and therefore have nothing in common with LUCA.
D)Their genes can be disrupted by transposons.

Question

Endosymbiotic bacteria have a reduced metabolic requirement as they are living within the host organism, which means they may have lost genes that were essential to early life-forms. So, analyzing their genomes may not give a clear picture of the minimal gene set required for early life.
