Question

what is cloning sites​

Answer 1

Answer:

Multiple cloning site

A multiple cloning site (MCS), also called a

polylinker, is a short segment of DNA which contains many (up to ~20) restriction sites - a standard feature of engineered plasmids.[1] Restriction sites within an MCS are typically unique, occurring only once within a given plasmid. The purpose of a MCS in a plasmid is to allow a piece of DNA to be inserted into that region.[2] A MCS is found in a variety of vectors, including cloning vectors to increase the number of copies of target DNA, and in expression vectors to create a protein product.[3] In expression vectors, the MCS is located downstream of the promoter.[2]
