...entire 5375 nucleotide sequence which determines the genetic make-up of the virus Phi-X174, the group at the Laboratory of Molecular Biology in Cambridge, England found that the same portions of the sequence could be 'read' in two different ways, each leading to the synthesis of a different protein...
...chain of twelve nucleotides, for example, each three successive nucleotides determine a protein. The Cambridge group found that the same nucleotide may be part of different triplet patterns beginning with the first in the sequence and the second or third...
