Operating on spiritual side of your individuality can bring you to the great heights, and drop you off if you neglect your spiritual identity. You are always looking for an opportunity to investigate the unknown, to use and show your mental abilities, to find the purpose and meaning of life. You want to grow wise and to understand people and things.
Typically, PCR consists of usually 20-40 repeated temperature changes, called cycles, where each cycles usually contains three steps. It is necessary to perform many cycles because that way the end results will consist mainly of the desired DNA.
Figure 5: The replication cycle repeats many times. The number of new copies of the DNA sequence of interest doubles with each three-step cycle. Thus, if the PCR process is repeated 40 or 50 times, even small samples of template DNA can yield millions of identical copies (Figure 5). PCR is an incredibly versatile technique with many practical applications.
