DNA Sketch Model

As we work further into the human body and system, we must work to understand one of the most key components to human function: DNA structure and function. To do this, we were given instruction about the basic components to DNA and asked to fit them together in a sketch that would demonstrate how it fit together to form a strand of DNA. The pictures included below are the "finished product" of this activity.

As you can see in the last picture, a nucleotide is shown. A nucleotide is the basic component of DNA, composed of dioxyribose, phosphate, and one Guanine, Cytosine, Adenine, or Thymine. Notice the "or" in that list. A nucleotide only contains one of the four listed, and can be found int the acronym GCAT. These then form a hydrogen bond with the opposite strand; the only possible combinations of pairings are Guanine with Cytosine, and Adenine with Thymine. Once the strands are bonded, they align themselves in a double helix shape, forming the common DNA perception. There you have it: the basics of DNA!
