Three interesting facts about DNA MPX STEM

On the last homework assignment, we were told to research DNA, to get the general knowledge of what DNA is, and what it is used for. Now, we are asked to narrow down our research to find some pieces of information that we do not currently know. For starters, I did not know that it was Rosalind Franklin’s discovery of the chemical structure of DNA that led to Crick and Watson’s double helix model. Currently, crick and Watson are credited for the discovery of the double helix model, without credit to Rosalind. Even though she played a major role in the discovery of it. If she had been alive longer, maybe she would have. Rosalind died at a young age die to the massive amounts of radiation she was exposed to constantly.

I was surprised to find out that red blood cells do not contain DNA. Every single part of your body contains DNA, except for red blood cells. It's funny, I would've thought that red blood cells would have DNA in them, because in a lot of crime and investigation tv shows the people use the bad persons blood to figure out stuff about them...I think. Either way I was very surprised because I would've thought that would be one of the parts of your body that would most likely have DNA in it.

The final, and most fascinating face that I now know is that a fast typist, working eight hours a day, would take 50 years to type out the human genome. 50 YEARS! That's absolutely crazy! It's truly amazing that our cells are copying any multiplying at a crazy rate, and every time they multiply themselves they have to copy the code perfectly every single time. Our cells do it almost perfectly throughout our whole lives.

DNA research MPX STEM

DNA stands for deoxyribonucleic acid.

DNA is found inside every cell in our body (apart from red blood cells).

Humans have roughly 100,000,000,000,000 (100 trillion cells).

If you unravelled all of your DNA from all of your cells and laid out the DNA end to
end, the strand would stretch from the Earth to the Sun hundreds of times

DNA is tightly coiled up and structured into 46 chromosomes.

DNA is made up of 4 building blocks The four letters in the DNA alphabet A, C, G and T are used to carry the instructions for making all organisms

 it was Rosalind Franklin’s discovery of the chemical structure of DNA that led to Crick and Watson’s double helix model.

DNA (deoxyribonucleic acid) was first isolated by the Swiss physician Friedrich Miescher in 1869.

Any two people share about 99.9 per cent of their DNA. It’s the other 0.1 per cent that makes us different from each other.

A fast typist, working eight hours a day, would take 50 years to type out the human genome.

Biological information is replicated as the two strands are separated. A significant portion of DNA (more than 98% for humans) is non-coding, meaning that these sections do not serve a function of encoding proteins.

The two strands of DNA run in opposite directions to each other and are therefore anti-parallel, one backbone being 3′ (three prime) and the other 5′ (five prime). This refers to the direction the 3rd and 5th carbon on the sugar molecule is facing.

Within cells, DNA is organized into long structures called chromosomes.

Scientists use DNA as a molecular tool to explore physical laws and theories

CNV reflection humanities




I feel that the dramatic element that worked well for us was the character development. Because our adaption to the book was to the point, we took out a lot of the background story and plot build up. We figured that the most important part of a adaptation is keeping its characters traits and character virtually the same, so we kept as much character as possible in the adaptation.
In our adaptation of the play, we did not really move around any parts of the plot in any way. We wanted it to be in the most chronological order that we could possibly make it in, so we tried to keep everything that happened in the book exactly like our adaptation. However, we did take out some events that happened in the book. It would be impossible to make an under ten minute video about a whole books plot, in depth.
We felt that the characterization of our adaptation reflected more of the characters traits and character, more than the actual book it's self. What I mean is that the actual characters were more identical to the characters in the actual book, than the plot and events were to its book counterpart.
Our play filled out all of the requirements, because the events that took place in the book were specifically chosen to be in our adaptation because of their importance in both the plot, and the elements of a good play/book. From beginning to end, each scene has a purpose for both the plot and the requirements of a play.
For the adaptation, there were defiantly things that both my partner and I were proud of, and not so proud of.  We were proud of the scene we depicted of the plane crashing, and Julie parachuting our of the plane. However. We were not so proud of the voices we had to do for Maddie and Julie. It was pretty weird.
