Adenine and guanine are double-ring molecules called purines, but cytosine, thymine and uracil are all pyrimidines: single rings. To maintain its orderly structure, single rings on one strand can only ...

The sequencing of the human genome at the turn of the 21st century was heralded as a monumental scientific achievement ...

The key shows the universal elements (hydrogen, oxygen, carbon and nitrogen); the four bases of the DNA molecule (adenine, cytosine, guanine and thymine) with their molecular structure ...
