question 34

Essay

Genome sequencing of the bacterial symbionts of animals has allowed us to compare the genomic features of several symbionts. The following data was collected on two insect symbionts:
Symbiont A: 0.4 Mb genome, 20% G+C content, missing or incomplete peptidoglycan synthesis and nucleotide synthesis pathways.
Symbiont B: 1.8 Mb genome, 40% G+C content, peptidoglycan and most nucleotide synthesis pathways complete.
What can you deduce about these two insect symbionts based on their genomes?
