Practice question
Question
A linear DNA fragment which has 3 restriction sites for BamH1, is labeled only at the 5/ end. This DNA is partially digested with BamH1 in such a way that all kinds of fragments are generated. Under these conditions, how many labeled and unlabeled fragments will be produced?
Explanation
In aptitude and reasoning, quantitative reasoning dictates that ratio, percentage and series logic determine correct calculation. Therefore 4 labeled and 6 unlabeled is correct as it meets mathematical and logical criteria, supported by mechanistic studies and conserved across related systems.
