Strings of dna in cell nuclei
WebMitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself. In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes. WebJan 21, 2024 · Each DNA molecule contains two DNA strands, which are twisted around one another to make a spiral-like shape called the double helix. Together, the phosphate groups and sugars form the sugar-phosphate backbone, …
