35S Promoter


For the traits encoded by the genes present in chromosomes to be useful to a cell, the information encoded by the DNA must be converted into messenger RNA (mRNA) that is then converted into useful proteins.  The promoter’s job is to help the cell know when and how much a gene can be translated into protein by the cell.  If a gene has no promoter, the gene can’t be used by the cell.  The S35 promoter is a particular type of promoter and was taken from a virus that infects plants like cauliflower and cabbage that is called the cauliflower mosaic virus (see also RNA).
