The bacteria which had mutation became resistant to the antibiotic and survived and keeps on increasing, promoting natural selection.

Explanation:

The bacteria rapidly divide, the chances of mutation in the gene increases manifold.

The strains of bacteria causing tuberculosis and staph infection got mutated at DNA level such that they became resistant to antibiotics when tested those susceptible did not survive. These mutations were not harmful to bacteria and the resultant bacteria survived.

These bacteria which survived and proliferated as the environment was in their favour.

Thus, Darwin's Theory of Natural Selection is acceptable here as it says if a mutation is occurring towards the increase in population, they will be selected ones.

Oksana_A [137]

Answer:

Human genome has various replicons.

Explanation:

A replicon which is a unit of DNA, has potential to get replicated independently. So, the DNA replication occurs simultaneously at various replicons as a result of which human genome takes much less time than estimated to get replicated .

In contrast to this, prokaryotes like E.coli have only one origin of replication and thus one replicon due to which replication is restricted to once per cell cycle.
