The specificity of the PCR depends crucially upon the primers. The following factors are important in choosing effective primers

Primers should be 17 to 30 nucleotides in length

A GC content of about 50% is ideal. For primers with a low GC content, it is desirable to choose a long primer to avoid a low melting

 temperature.

Sequences with long runs (i.e., more than three or four) of a single nucleotide should be avoided.

Species richness of both plants and animals, often, but not always, increases as succession proceeds.
