DNA Replication and Repair
Reproduction is a property of all
DNA duplicates by a process called DNA
The DNA replication machinery is also
used for DNA repair.

which captured and utilized energy by oxygenindependent metabolism.
Oxygen accumulated in the primitive
atmosphere after cyanobacteria appeared.
