The correct way to complete this graph is to add cytosine and thymine on the first DNA string, adenine, and guanine on the second string, and 3' and 5', in the bottom.
What elements are missing?
The main elements missing are the nucleobases that compose DNA. These are the four basic nucleobases:
- Adenine
- Guanine
- Thymine
- Cytosine
Moreover, these nucleobases pair up in the following way:
- Adenine always pairs up with thymine.
- Cytosine always pairs up with guanine.
Based on this, the elements that are missing are:
- Cytosine
- Thymine
- Adenine
- Guanine
Besides this, the numbers 5' and 3' should be placed to mark both the beginning and end of this DNA string. This should be placed in an opposite way as the first string, this means 3' and 5'.
