When transcription takes place RNA is formed from DNA. This happens because DNA can not fit through nuclear pores while RNA can. The DNA strands unzip and one stand is used as template for the mRNA. The mRNA ends up being complementary to that strand of DNA. The mRNA then moves out of the nucleus into the cytoplasm.
Translation
Translation takes pace in the cytoplasm on the ribosomes. The mRNA that was formed in the nucleus moves out to the ribosomes to carry the message of DNA. The RNA strand then is fed through the ribosome like a tape measure and the amino acids are assembled.. Those amino acids then link together to form proteins.
