Purine = Adenine (A), Guanine (G)
Pyrimidine =Thymine (T), Cytosine (C)
*All 3 have a Y

Sugar – Deoxyribose
Phosphate Groups (spacer)
Nitrogen Bases – Code of Life in ATCG
Thymine always pairs with Adenine
Guanine always pairs with Cytosine
Which structure in the backbone is directly attached to the Nitrogen bases?
What are the “spacers” between each step?
Why were Mike&Ikes a good example for the purines?
Why were Skittles a good example for the pyrimidines?
Important during meiosis & mitosis because it makes sure the daughter cells have the appropriate number of chromosomes.
If the original strand of DNA is AATTGGCC
The complementary strand of DNA is TTAACCGG
