Polycistronic
An mRNA that encodes several discrete gene products.
Polylinker
A short, synthetic DNA sequence containing several restriction enzyme recognition sites. Polylinkers facilitate cloning into plasmid or phage vectors.
Polycistronic message Refers to an mrna molecule that encodes for more than one protein.
Polyclonal antibodies Antibodies that are the products of many different populations of antibodyproducing cells.
polycistronic mRNAs are very rare

Cistron: A DNA segment coding for a specific polypeptide, and includes its own start and stop codons. When an mRNA encodes two or more proteins, it is called polycistronic.
