Question

Multicellular organisms use cell division and mitosis for growth, maintenance, and repair of cells and tissues. There are few cells in the body that do not undergo mitosis: most somatic cells divide regularly, some more than others. Single-celled organisms may use cell division as their method of reproduction. Regardless of the reason for mitosis, the process ensures genetic continuity. Consider the model of the cell cycle. Which details from the model best support the argument that cell division promotes genetic continuity?

A mitosis and cytokinesismitosis and cytokinesis
B DNA restriction point and inclusion of G0DNA restriction point and inclusion of G 0
C checkpoints throughout and replication during mitosischeckpoints throughout and replication during mitosis
D the template DNA provides for making copies during replication

Answer 1

To support the argument that cell division promotes genetic continuity, the best response would be:

**D the template DNA provides for making copies during replication**

This detail highlights how the DNA is replicated during cell division, ensuring that each daughter cell receives an identical copy of the genetic material, thus promoting genetic continuity.
