Simple Diagram Of Molecular Structure Of Dna. Dna is made up of subunits which scientists called nucleotides. The two chains are held together by hydrogen bonds between the nitrogenous bases.
Notice that the individual bases have been identified by the first letters of the base names. In all cellular organisms dna consists of two polynucleotide strands forming a double helix. The bases a g c g form the rungs of the ladder.
Each nucleotide is made up of a sugar a phosphate and a base.
The molecule has two different edges termed the 3 prime edge and the 5 prime edge. Day 2 kahoot for topic 32 again this time including lipids. Dna also includes sugars and phosphate groups made of phosphorus and oxygen. Draw the structure of one nucleotide.
