Study Notes

Molecular Cloning

Restriction/Digestion Enzymes

Function in molecular cloning: to cleave DNA molecules at specific recognition sites, producing compatible ends for ligation
Provide protection to bacteria against invading viruses: by breaking down viral DNA, preventing viral replication

Characteristics

Recognize and cleave specific DNA sequences: typically 4-8 base pair palindromic sequences
Used mainly in in-vitro experiments: to manipulate DNA in a controlled environment

Vectors

Role in molecular cloning: to clone and replicate DNA fragments in a host organism
Main function: to provide a mechanism for DNA replication and transmission

Ligation

Purpose in molecular cloning: to join two DNA fragments with compatible ends, forming a recombinant DNA molecule
