what is the first step in cell division
Cell cycle Mitosis is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two nuclei.[7] During the process of mitosis the pairs of chromosomes condense and attach to fibers that pull the sister chromatids to opposite sides of the cell.[8]
Origin of replication DNA replication may proceed from this point bidirectionally or unidirectionally.[3]
Order of operations These mnemonics may be misleading when written this way,[6] especially if the user is not aware that multiplication and division are of equal precedence, as are addition and subtraction. Using any of the above rules in the order "addition first, subtraction afterward" would incorrectly evaluate the expression[6]
Cell theory The first of these tenets is disputed, as non-cellular entities such as viruses are sometimes considered life-forms.[1]
