Answer:
These data supported the hypothesis that the code is a triplet
Step-by-step 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.
