4x There are few cells in the body that do not undergo mitosis: most somatic cells divide regularly, some more than others. Take for example the cells that line the digestive tract.These cells must be replaced because they are constantly eroded by the movement of food through the tract. What mechanism(s) is/are in place to ensure that these cells are exact copies of the mother cell? A DNA restriction point B DNA template plus DNA damage checkpoints C the template DNA provides for making copies D quiescence checks for damage

The correct answer is C. The template DNA provides for making copies.<br /><br />Explanation:<br /><br />A. DNA restriction point is not the correct answer. The restriction point is a point in the cell cycle where the cell commits to completing the cycle and dividing. It is not directly involved in ensuring that daughter cells are exact copies of the mother cell.<br /><br />B. DNA template plus DNA damage checkpoints is not the correct answer. While DNA damage checkpoints are mechanisms that ensure the integrity of the DNA before cell division, they do not ensure that daughter cells are exact copies of the mother cell.<br /><br />C. The template DNA provides for making copies is the correct answer. During mitosis, the DNA in the mother cell is replicated, and the resulting copies are distributed to the daughter cells. This ensures that the daughter cells are exact copies of the mother cell.<br /><br />D. Quiescence checks for damage is not the correct answer. Quiescence is a state of dormancy or inactivity, and it is not directly involved in ensuring that daughter cells are exact copies of the mother cell.<br /><br />Therefore, the correct answer is C. The template DNA provides for making copies.
