- DFor initiation, there is another specific tRNA that is referred to as initiator tRNA.
Correct answer
A. James Watson postulated the presence of an adapter molecule that would on one hand read the code and on other
Step-by-step solution
From the very beginning of the proposition of code, it was clear to Francis Crick that there has to be a mechanism to read the code and also to link it to the amino acids, because amino acids have no structural specialities to read the code uniquely. He postulated the presence of an adapter molecule that would on one hand read the code and on other hand would bind to specific amino acids. The tRNA, then called sRNA (soluble RNA), was known before the genetic code was postulated. However, its role as an adapter mole
