DNA carries all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein. In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).

Answer:
The correct answer is "Shine Dalgarno sequence".
Explanation:
- A consensus originally characterized throughout the mRNAs to Escherichia coli seems to be the Shine-Dalgarno chain.  
- Proteins manufactured through sequences comprising unique sequences became generated more gradually or slowly than similar proteins encoded of separate but interchangeable codons from genes, researchers observed.
