Edible DNA 

1. what is DNA?

• Deoxyribonucleic acid or mostly known as DNA, is a material that is found in all living things. DNA helps produce cells un your body, plants and more. DNA  stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells. all this information is distributed along your 46 chromosomes. 
• DNA is shaped in a double helix . The 2 sides of the DNA ladder are made up of sugar and phosphate.
• the colored cylinders in the DNA are made up of 4 nitrogen bases: adenine, cytosine, guanine, and thymine.
• 
• In our edible DNA , we used marshmallows to show the different nitrogen bases

2. What does DNA DO?

• DNA is the creator of all living things. you, me, animals, plants, you name it. DNA converts information to proteins that help make your body.  DNA carries all your genetic information, that makes you, you. This could be : hair color, eye, nose, face shape. Anything that can be passed down from your family. DNA does a great  job of replicating itself  The original DNA strands from the double helix is the one created before the duplication;
• before

• Aftet
• DNA is a key part of reproduction in which genetic hereditary, occurs through the passing down of DNA from your parents to you.

  3. How easily does DNA copy itself

• The original DNA strands from the double helix is the one created before the duplication.
• {insert} The leading strand is always combining when the other lagging strand is combined in small pieces that eventually join together to complete the new copy of the original DNA. 
• DNA is a molecule that can be replicated many times, and most pf the time it turns out perfect.f .  replication uses DNA polymerases which are molecules specifically dedicated to just copying DNA. Replicating all of the DNA in a single human cell takes several hours of just pure copying time. 
•  the 3 steps that are used every single time a DNA replicates itself.
• “the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands.”

• I find it so interesting how 1 single DNA, can duplicate itself into thousands. considering our body is made up of thousand of DNA’s.

1. What further questions do you have after building this model?

• Is DNA the only molecule that can carry our genetic information?
• How was DNA discovered and studied on,  in the past?

• • What answers can you find to your questions
  • 1. DNA is the only molecule that carries our genetic information. it is DNA’s job to duplicate itself as many times, to make sure we have all our information we need.
  • 2. Friedrich Miescher was the person who discovered DNA. he was initially trying to learn about white blood cells, but instead discovered DNA. While Miescher was the first to define DNA , several other researchers and scientists have contributed to our r understanding of DNA as we know it today. And it wasn’t until the early 1940s that DNA’s role in genetic inheritance was even begun to be researched and understood.

conclusion

In conclusion I loved this lab. because we had just started our unit on biology, I didn’t completely understand what was going on. But after doing this lab I have learned so much: how DNA looks, the significates of the color(the nitrogen bases), how it duplicates. And of course the best part, was getting to eat our DNA. HAHA.
