Describe the function of each of the following in protein synthesis; rrna, mrna, and trna

Proteins synthesis requires transcription of DNA (containing information) to mRNA then this goes out of the cell’s nucleus to cytoplasm; and translation of mRNA together with ribosome and tRNA to synthesize proteins. Further steps are the following: 1) One side of DNA strand is copied to become mRNA (messenger RNA). 2) mRNA goes out the cell’s nucleus, next to cytoplasm and then to ribosome. 3) mRNA works with ribosome’s 3 bases at the same time. 4) tRNA (transfer RNA) connects with available DNA bases. 5) tRNA releases the amino acids which in turn combines with the other produced amino acid chains from different DNAs. 

The answer is joseph is observing the colour of the reaction mixture to see whether proteins are present in the given solution.
