A DNA library is a collection of DNA fragments cloned into a vector, representing an organism's genetic material.
Definition
Definition
DNA libraries are used to study an organism's genetic information, identify new genes, and understand evolutionary relationships.
Purpose
Purpose
There are three main types of DNA libraries: genomic, cDNA, and chromosomal libraries.
Types
Types
DNA libraries are constructed by fragmenting DNA, ligating fragments into a vector, and transfecting vectors into host cells.
Construction
Construction
A DNA library represents a snapshot of an organism's genetic material at a particular point in time.
Representation
Representation
DNA libraries can contain tens of thousands to millions of DNA fragments.
Size
Size
DNA libraries are typically stored in a frozen state to preserve the DNA for future use.
Storage
Storage
DNA libraries can be screened for specific genes or sequences using probes or PCR.
Screening
Screening
DNA libraries have applications in medicine, agriculture, biotechnology, and evolutionary biology.
