Each (both large and small) colony is carefully counted (using magnifying colony counter if needed). Each colony represents a “colony-forming unit” (CFU). For accurate counts, the optimum count should be within the range of 30-300 colonies/plate. To insure a countable plate a series of dilutions should be plated.
Answer: Chargaff's observation was an important clue to the A-T and G-C pairings that Watson and Crick eventually proposed. ...

Explanation:
<span>The lytic cycle is a six-stage cycle. In the first stage, called "penetration", the virus injects its own nucleic acid into ahost cell. In some viruses this genetic material is circularand mimics a bacterial plasmid. The virus hijacks the cell's replication and translation mechanisms, using them to make more viruses.</span>
