DNA (deoxyribonucleic acid) is the main component of human genetic material. It is formed by combining four parts known as Adenine (A), Cytosine (C), Guanine (G) and Thymine (T) respectively.  These ‘parts’ are called bases of DNA and they combine in thousands of possible sequences to provide genetic variability.  In the early 80s, a fifth base was added to the four classic bases of DNA.  … Continue reading Researchers state they have discovered the sixth DNA base in eukaryotes.
