Question

4. If a plasmid is cut once, how many fragments, or sections, of DNA will be produced? Provide a drawing to

Answer 1

Answer:

4 - 1 fragment

5 - 2 fragments

Explanation:

A plasmid is a molecule of desoxyribonucleic acid (DNA). It has a circular shape. When you cut a circle, it is linealized. So, if you cut a circle once, you will obtain 1 line (1 fragment). If you cut a circle twice, 2 lines or fragments are produced.

Thus, the answers are:

4 - If you cut once ⇒ 1 fragment (see drawing in attachment 1)

5 - If you cut twice ⇒ 2 fragments (see drawing in attachment 2)
