Gene Check

DNA is genetic material of living organisms. Major component of DNA is polynucleotides, including guanine (G), adenine (A), thymine (T), or cytosine (C).

According to base pairing rules (A with T and C with G), hydrogen bonds bind the nitrogenous bases of the two separate polynucleotide strands. An AT base pair with two hydrogen bonds, a GC base pair with three hydrogen bonds. In this game, you can learn the correct base pairing of nucleotides, and hydrogen bonds between the base pairs.
