A fourth type of restriction enzyme is identified that cleaves at precise locations like a type II enzyme, but it also occasionally makes mistakes and cuts elsewhere. Would this type of enzyme be a useful enzyme to use in molecular cloning?
A. Yes, because it cuts correctly sometimes. B. No, because it is a precise enzyme. C. No, because cutting mistakes could lead to incorrect cloning. D. Yes, because cutting mistakes don't matter in molecular cloning.

Why is possible to detect the mutation causing Huntington disease at any age?
A) It is possible to detect the mutation causing Huntington disease at any age because it is a single-gene disorder. B) It is possible to detect the mutation causing Huntington disease at any age because it affects consecutive generations. C) It is possible to detect the mutation causing Huntington disease at any age because it is caused by the mutation of linked genes. D) It is possible to detect the mutation causing Huntington disease at any age because it is influenced by the immediate environment.
