Answer:
Expose a sample of E. coli to streptomycin by inoculating it onto a streptomycin positive plate. Any colonies that grow will carry a mutation for resistance.
Explanation:
--
A cell spends the majority of its time in interphase because during this period the cell grows and synthesizes materials required during and after its division. During interphase, the cell duplicates its genetic material.
The cell cycle can be divided into a long interphase and a short mitotic (M) phase.
The interphase can in turn be divided into three phases: Growth 1 (G1) phase, Synthesis (S) phase and Growth 2 (G2) phase.
During the S phase, the cell duplicates its genetic material, which is sharply controlled by different cellular mechanisms (e.g., checkpoint mechanisms).
During G1 and G2 phases, the cell synthesizes all the proteins required during the M phase and after cell division.
