How do bases pair in dna
WebThe DNA bases pair together: A-T, T-A, G-C and C-G. DNA is arranged in a double helix structure. A gene is a short section of DNA that is the genetic code for a characteristic. WebThe nucleotide bases pair up to make rungs of the ladder, while the sugar and phosphate molecules make the sides. The bases have different shapes and pair up together in specific combinations: A pairs with T, and C pairs with G to make base pairs. Put three billion of these base pairs together in the right order, and you have a complete set of ...
