Afourth 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?

No, in molecular cloning cutting mistakes can lead to in correct ligation

C) No, because cutting mistakes could lead to incorrect cloning.

Explanation:

in molecular cloning, if you want to insert a specific gene of interest in to specific vector, the selection of enzyme and strategy before that is very important.  The restriction enzyme should be selected which restrict at the desired location in the cloning sites. Any mistake in these selection or undesirable mutation mistakes can lead to in correct or unsuccessful cloning results.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
