Press release assignment

Press release assignment

Should be 300-400 words.

About: evolution and natural selection to the public by means of describing the PTC gene experiment.

Write a press release, make sure you have all five W’s in your story (who, what, where, when, and why). In journalism. And that you have a catchy headline.

Your goal is to make the results and discussion section into a story that is accurate and interesting to the public. Your press release should include ideas about evolution and natural selection.

  • It’s very similar to a news story
  • You want to answer the (who, what, where, when, and why)
  • The key is to get the most important news right up at the top, it called inverted pyramid style.
  • News should be most important at the top, least at the bottom.
  • First paragraph is the main news, so this is usually the what (what is this about?) or the why (why are we talking about this?)



The Rubric for the assignment:



  • What the question of interest is and how it is answered
  • Why this is of interest to the general public
  • Who the research impacts and who did the research?
  • The time line related to the descriptions
  • Where the research took place and where the research relates to?


Inverted Pyramid style:

  • Put the important information, what and why (at the top of the press release)


Content and style:

  • Relate scientific evidence to natural selection and/or evolution
  • Potential for creating public interest.
  • Accurate discussion of scientific evidence produced in our experiments present.



(These is the PTC results and discussion that may help to complete the press release assignment)



Determination of The Genotype.






DNA Replication and PCR similarities:

DNA Replication and PCR differences:

Both involves a template strand.

Length of DNA

Both processes need DNTPS

 DNA polymerase enzyme of their function.

Types of polymerase

Both are involved in increasing number of copies of parental

DNA replication



In each step of PCR

  • Step1:  Heat.
  • Step2: Annealing primer to target sequence.
  • Step3: Extension.
  • Step4: End of the first PGR cycle.



The reason for each step of PCR:

  • Step1: heat up to 95 degree.
  • Step2:
  • Thermal cycler cools down to 50 degree.
  • Step3: change the temperature to 72 degree.
  • Step4: the same 3 steps were repeated.
  • Step5: desired products begin to appear.
  • Cycle four.



The purpose of this study is to determine the PTC genotype. The two most common alleles differ is PAV and AVI. In our experiment for this study the results show that without DNA cells could not reproduce and the high heat may kill cells. For each person, its necessary to have fresh micropipette tips because when the plunger pressed again, the liquid is dispensed. In figure2, in each step of PCR are important. By using PCR, DNA sequence can be amplified a lot of times producing enough DNA copies. Furthermore, PCR requires a DNA polymerase enzyme that makes new standard of DNA. While complementary base pairing is necessary in this study, which it is the bond between genuine and cytosine.
