Protein Synthesis

  1. How is mRNA different from DNA 

DNA arranged A,T,C,G into three letter words that we can call DNA triplets and mRNA copies DNA instructions where any given gene is made during translation. The message is now called RNA language and DNA triplets have been subscribed into a mRNA strand in three letter words called codons.

2. Describe the process of transcription

Transcription is broken into three phases, the first phase is unwinding and unzipping of DNA. The second step is complimentary base pairing and the third phase is separation from DNA and the final product is an identical daughter cell.

3. How did todays activity do a good job of modelling the process of RNA transcription? In what ways was our model accurate? 

This lab was a good example because it was very hands on and I think it helped me understand transcription better because we had to translate from DNA to RNA because we actually had to do it instead of just a lesson. Our model was accurate because it showed the translation of DNA to RNA in a moving visual model.

4. Describe the process of translation

The first step of translation is gong through initiation, this involves mRNA being held by the ribosome. Next is elongation and this is when the amino acid chain continues to grow, A site reads the next mRNA codon and brings the matching tRNA. The final step of transcription is termination where mRNA codon us a stop codon and there is no tRNA for a stop codon. The ribosome lets go of the mRNA and tRNA lets go of the polypeptide

5. How did today’s activity do a good job of modelling  the process of translation? In what ways was out model accurate? 

I think this model was good because for visual learners it gives you more of an understanding so you can memorize better for testing.
