Expression library:

1. An expression library is a collection of DNA that can be expressed in masses.
2. Several enzymatic methods are used to yield a population of DNA, RNA, or protein products that can be screened for individuals displaying desirable properties.
3. The DNA sequences present in an expression library can be of natural or synthetic origin.
4. Expression libraries require complementary DNA or cDNA to ensure whether the insert is truly a gene or not.
