Genetic message =C (triplets are groups of 3 nucleotides)
Promoter = B (this region is a section of DNA 100-1000 base pairs long)
Polysome =E (mRNA molecules hold these together)
Exon =A (EXons are what will be EXpressed)
Genetic code = F (these will become 1 of 20 different amino acids)
Intron = D (INtrons will stay INside the nucleus so they won't get expressed)
