Problem:
Bacteria have many traits that are of economic interest. A new strain of the bacterial species Shinorhizobium meliloti leadii (one of many symbiotic bacteria that fix nitrogen in the roots of legumes) has been found to produce and exude a polysaccharide compound that binds to toxic lead. This compound, if it can be produced economically, could be useful for decontaminating soil that contains lead and other toxic metals.
Required:
Question 1: Design an experiment that would prove which macromolecule (DNA, RNA, or Protein) carries the information for making this lead-binding polysaccharide.
Question 2: If you knew that 3 different proteins are required to make this polysaccharide, each only found in the new strain, Streptococcus meliloti leadii, how would you need to adjust your experiment?
Please provide discription of all the answers.
