Students add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules. Students watch molecular model animations to see the effect of heating and cooling on the molecules of a liquid. Students will also draw their own molecular model.
DNA replication is the process of DNA being copied to make more DNA. Transcription is the process of DNA being read and RNA being made based on that particular DNA strand.Translation is taking the RNA just made and using it to make a protein.One DNA strand can make as many copies of RNA as it needs, and one RNA strand can make as many proteins as it needs.ranscription is the process of DNA being read and RNA being made based on that particular DNA strand. Translation is taking the RNA just made and using it to make a protein.
The stretch of DNA that is transcribed into an RNA molecule is called transcription unit. Transcription has some proofreading mechanisms, but they are fewer and less effective than the controls for DNA; therefore, transcription has a lower copying fidelity than DNA replication.ut to answer your question to the point, only one strand of DNA is copied during transcription for practical reasons. The one strand that is copied will result to a duplicate copy of the other strand that WAS NOT copied.
