Reconstructing evolutionary relationships helps in differentiating between primitive and derived characteristics.

The relative percentage of genes devoted to protein synthesis in small-genome organisms is high compared with that of large-genome organisms.

Explain the terms "core genome" and "pan genome" and describe how each contributes to the genome of a bacterial species.Give an example of genes that are part of a core genome versus those that are more often in the pan genome.

Despite having smaller genomes,the protozoans Paramecium and Trichomonas have significantly more genes than humans.

With modern molecular techniques,it is now possible to completely assemble a genome from a single cell.
