It can be explained with the help of base-pair complementary rule which states that adenine will always base-pair with thymine and guanine will always base-pair with cytosine.
Adenine bonds with thymine through two hydrogen bonds and guanine bonds with cytosine through three hydrogen bonds.
Little confused on the question but if I am suppose to match the question with one of the statements I would choose that “The cell membrane pinches in to form two new cells.” - what happens during cytokinesis.
