WebbProblem : The number of replication forks in a DNA helix is often an even number. Explain this finding. Since replication origins are usually not found at the end of a helix, but rather internally to a helix, one replication origin leads to the formation of two replication forks. Replication forks, thus, are usually found in pairs. Webb8 aug. 2012 · Overview of Steps in Analyzing DNA Evidence. Several basic steps are performed during DNA testing regardless of the type of test being done.
