Protein Synthesis

The process of transcription is used for DNA sequences to be copied and then to make RNA molecules. Which are In these steps first it unwinds and unzips. second the complimentary base pairs, pair  with DNA then third it separates from DNA. What  is unzipping and unwinding it is when the DNA helicase unwinds the strand. Which then the complimentary base pairing, is when nucleotides that are not bound the complimentary base pairs with them on the backbone which has the DNA and the instructions. Then the joining is when RNA polymerase makes covalent bonds between “adjacent” nucleotides which is then on the new RNA strand which then this make the DNA molecule form into a double helix and the RNA is now edited then leaves the nucleus. Then the separation from DNA is formed by RNA polymerase which which gives the single strand template that is then used for transcription.

 

The process on translation happens with in three steps the first is initiation than elongation than termination. Initiation is when the messenger RNA bonds or binds to a smaller subunit of ribosome which then goes and bonds to then to two more subunits join together. Then elongation is when a ribosome holds some messanger RNA then reads its codons at the P and A site. Then it is then transferred to the transfer RNA and then where the amino acid chain grows and becomes longer. Termination is where the elongation cycle continues until the messanger RNA codon is at a site for which there is no complimentary transfer RNA then a stop codon which no new amino acids is added to the chained then the polypeptide dissociates from the ribosome.

Our model accurately reflects the process of protein synthesis because we showed each step one by one. Also it accurately shows the steps of the protein synthesis also the translation and transcription. However, it also misrepresented it because it doesn’t go into detail of every step of the process as it is vague and isn’t that useful. Only if someone is first trying to use this as a form of learning about protein synthesis. Some changes that I would make to the modeling activity is for there to make it better representing the processes. Which would be by making each step go a little deeper into the activity and for the instructions to be better labelled in which what to do. Since the first time we did the activity we did it wrong and I feel for people to be more successful in this, would be if the activity was better labelled and descriptive in what needs to be done and what steps to take. I feel like these models are only an effective way to communicate to non-scientific audience in only some cases. This technique only works for visual learners because for some people it needs to be written out in words and for it to be clearly stated. While visual diagrams sometimes can be hard for them since they have to put clues together and try to understand and think about the subject. Which would take a lot of more time and is very much harder for them. While for those who are visual learners it can be very helpful and let them learn and understand a lot. However it really does matter what type of learner they are and what is the best for them.
