in the early 1900s a scientist hypothesized a link between dna and the production of proteins in the cytoplasm. however, the fact that dna could not be found outside the nucleus led scientists to believe that another substance was also involved in the synthesis of protein in the cytoplasm. in the 1940s scientists performed an experiment that ultimately identified the site of protein synthesis. they also identified the molecule responsible for transporting information form the nucleus to the site of protein synthesis. what was this newly identified molecule?
a) a gene
b) mrna
c) atp
d) thymine
