The discoverers of DNA were not
James D Watson and Francis Crick. They are the first scientist to formulate an
accurate description of the DNA’s (deoxyribonucleic acid) complex ,
double-helical structure. They discovered that base pairing nucleotides must
be; adenine and thymine; and cytosine and guanine. These base pairs are held
together by a hydrogen bond, atype of chemical reaction that s easy to break
and easy to reform. The statement is “DNA
is a double helix made of two strands linked together with hydrogen
bonds.”
