When scientists were attempting to determine the structure of the genetic code, crick and coworkers found that when three base additions or three base deletions occurred in a single gene, the wild-type phenotype was sometimes restored. these data supported the hypothesis that

These data supported the hypothesis that the code is a triplet

Explanation:

The investigation of Crick and coworkers that were working with the additions and deletions in a single gene, showed that it was a triplet code, this means that a triplet code can make a genetic code of 64 different combinations and as also shown in their study as they tried to find out how did it work they also discovered that it could restore the line of three that had been deleted or adapt to the added new line.
