<span>It's necessary for DNA to replicate as the first step in mitosis because the whole point of mitosis is to create new cells, exactly like the old ones. Since DNA has all the genetic information that makes cells do what they do, it's necessary to replicate them in the act of mitosis.</span>

DNA is a macromolecule composed of nucleotides which carry the genetic instructions used in the growth, development, functioning and reproduction of the cell. One of the most important characteristics of DNA is its ability to make several copies of it (to be copied via the process of replication). When the cell divides into two it must carry each copy of DNA into the divided cells. Through replication, the DNA transfers the information necessary for creating an exact copy of it in the new daughter cell. The transfer of the DNA to the next generation of cells is essential for the function of the whole organism.

<span>DNA replication will make the organism to reproduce the genetic code and transfer it to the next generation (through the reproduction) and thus, to continue the species. </span>

The appropriate answer in the KREBS CYCLE. The Krebs cycle is also called the citric acid cycle. It is a cyclic reaction series involving several carboxylic acids in the mitochondrial matrix. Acetyl groups are oxidized to carbon dioxide while reducing specific co-enzymes. These co-enzymes are now available for ATP synthesis. This cycle or process occurs in the cells mitochondria.
