DNA and Protein Synthesis

  1. DNA stands for Deoxyribonucleic acid
  • The structure has 2 backbones that are made of sugar-phosphate units and the complimentary bases extend inward and hydrogen bond.

  • The backbone strands are antiparallel and the structure twists into a double helix shape which is the twisted shape you see below.

  • Sections of DNA are called Genes and each gene are instructions to build a protein
  • Each gene is about 1000 nucleotides long
  • The DNA strands are packed into chromosomes within the nucleus
  • Each chromosome is 1 DNA molecule which is 85,000,000 nucleotides long.

2. This activity helps with understanding the parts of the DNA molecules like the sugar-phosphate backbone and the complimentary bases. The sugar-phosphate backbone and where the phosphate goes was a good way to help understanding and also whether the bases were double or single ringed were good as well. To make it more accurate you would need more details of each part, for example showing the double helix shape better. In the photo below the blue strips with pink represent the sugar-phosphate backbone and the white pipe cleaners with the beads represent the bases and have either 1 or 2 beads depending on if the base is double or single ringed.

 

 

 

 

 

 

 

  • DNA replication occurs before cell division, the photo below shows the separation of  DNA that occurs within the nucleus and you can see the green triangle of play dough acting as the helicase to separate the DNA.

  • The DNA helicase first unzips the the DNA separating into two strands, from there the DNA polymerase pairs the complimentary bases together, and the DNA ligase joins together the nucleotides creating a new strand of DNA. The process for leading and lagging strands are different because the backbones of DNA are antiparallel. In our photo it shows the second backbone for a new DNA molecule is being created, in addition to the first photo you see the red block acting as the polymerase that connect the two strands together by the complimentary bases as well as the blue circles which represent ligase which join the nucleotides together.

 

  • For the complimentary bases we just twisted the white pipe cleaners that had the beads together which don’t really show the hydrogen bonds very accurately. Also for the adjacent nucleotides it was just a single blue pipe cleaner with the “phosphate” beads and did not show each nucleotide separately, which affects to visual representation for the function of ligase.n is a broad sense this was a good visual representation of how DNA is formed and the parts of DNA. It was also good to see the process of DNA replication, but it is not very effective in showing the functions for ligase and polymerase without explanation.

                                        Following the System

By Jesse Lee

 

Bigger game, bigger place, bigger system.

Bigger is not always better.

More recognized is not always credible.

More teammates, more competitors, single player.

Good, but want to improve. Wasn’t taught. Was told.

The reason for one’s fall is how they rose.

Put in a system for many.

But many only followed a single standard.

Drained of purpose, drained of reasoning.

The hunger begins to starve.

The system is just a clock counting.

How long will you last? Can you last?

Now your last. Will you stay at the bottom?

With a broken base.

Or rebuild knowing that this was once your happy place.

Stay down knowing everything is corrupt.

But when at the bottom,

The only place to go is up.

My Reflection/Discussion:

 

Poem Composition:

The poem I enjoyed most of the blood and roses poems was He Sits Down on the Floor of a School for the Retarded. This poem was one of the few that spoke about the roses side for things that are intangible, and everyone could relate to. Human connection is something we all have some sort of desire for and the poet depicted it so well through his imagery. He shows the human connection between two different people that don’t know each other and how meaningful this type of connection can be. He also shows how one needs to put aside all of the societal norms and the effects of other people’s views to be able to have a connection like this. This is so relevant in today’s world because everyone sees what people can do and socially connected through technology. What I get from this through a modern-day point of view is that no matter what other people think and how connected we are through technology; we will always have desire for intangible human connection, and this is something that every human no matter what type of person they are wants to feel. This poem definitely is about the roses side, but still acknowledges some of the blood within our world through societal norms and perspectives and we also see some of the main characters arrogance through him thinking that the most natural thing about humans which is affection is unnatural. This is most likely from the conformity from society and being accustomed to what society thinks.

The Math Pre-calculus 12 Transformations unit has helped me improve my critical thinking because I have to analyze graphs and write down what is happening to each function. It has improved my creative thinking because I have to draw the graphs and now. know how to manipulate it where I could move all types of graphs up, down, left, or right. It has improved my communication skills because I verbalize what it happening to each function and once I verbalize I can then use replacement language to show what I am doing.

This is my article

This article really interests me because it talked about how materialistic things only provide happiness temporarily no matter how many promises of happiness the object has. For Killingsworth what truly gave him happiness were the moments and experiences he had. What I liked about the authors style of writing was that it was very factual and almost meaningful, to the point where I could relate to when he talked about how long lasting memories and experiences can make you happy. This made me think of my own past experiences. This article is sort scientific in the way that it talks about psychology and so it really talks about how we think of happiness and what truly makes people happy. They said that living in a moment is not really possible, but we should live waiting for an experience. I relate this to the human condition because today all of us are so invested in technology that it becomes our lives, but if we were to put down our phones and create experiences that truly make us happy then our existence would be more meaningful.

I was interested in this topic because first the title was intriguing, but once I started reading I realized that this is a very serious topic. The topic itself was quite interesting because although it talked about suicide, it transitioned from conveying a dark mood because they talked about the things they found in Tiffany’s room to a more sorrow mood as the author explained that in the past he was on the other side of hearing things about other peoples family member passing away. I liked how the author spoke in. first person and although his imagery wasn’t extremely descriptive, as I was reading it still clearly depicted an image in my head. When the author said, “And you can’t really say, ‘There used to be six,’ ” I told my sister Lisa. “It just makes people uncomfortable.”, I was totally able to relate because if a person has experienced loss before, whether you’re the one hearing or talking about what happened, it makes the interaction a bit awkward and uncomfortable.
