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 frequently 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? Responses A DNA restriction pointDNA restriction point B DNA template plus DNA damage checkpointsDNA template plus DNA damage checkpoints C the template DNA provides for making copiesthe template DNA provides for making copies D quiescence checks for damage
C) the template DNA provides for making copies
During mitosis, the cell replicates its DNA, ensuring that each daughter cell receives an exact copy of the mother cell's genetic material. The template DNA serves as a blueprint for creating new copies of the DNA during cell division, resulting in exact copies of the mother cell. This process helps to maintain the genetic integrity of the cells lining the digestive tract and ensures that they function properly in replacing damaged or worn-out cells.
