Preparation of genomic library (flowchart with description)

Solution:

DNA or genomic library is the total amount of DNA collected from a single organism. 

Steps to prepare a genomic library are as follows:

• In order to prepare a genomic library, the organism's DNA needs to be extracted from the cell.
• Next, the DNA is digested with a restriction enzyme.
• This ensures that the DNA is cut into fragments of the specific size. The fragments are then inserted into the vector using DNA ligase.[1
• The fragments of DNA are collected and stored for their use in the molecular cloning.
• This DNA is stored in vectors containing various fragments of inserted DNA.
• These vectors are then maintained in the host cell mainly bacteria like E.coli.
• This allows easy amplification and extraction of the clones.
